I had a dream a year ago in which I was traveling at very high speed towards an edge of our universe. In the dream I entered a null space before entering the next universe in which all star systems obeyed solid state physics type laws: stars formed an outer lattice and planets in small lattices around stars.

After traveling through the second universe in my dream, I then entered a third universe that was more compact because space was curving back onto itself in a way that was not understandable but I kept looping back to where I was before. When I woke up I thought I was dreaming of a very high dimensional space where everything was happening in lower dimensional manifolds curving through that space where “all the action was.”

Definitely one of my better dreams!

Wow, if you’re having these dreams without the aid of substances, I envy you. The most intellectual dreams I seem to be able to come up with “unenhanced” are falling off buildings and being late to college exams while having no pants on.

My favorite are the dreams I have before a semester starts: it is the end of the semester, and I've just discovered I've forgotten about an entire class for most of the semester. Then I wake up.

I'm in my 40s. For a good long while, my recurring school dream was that my high school discovered that I didn't actually finish correctly, and because that invalidates my college degrees (in dream logic land), I can't do my job until I go back and finish high school properly.

For some reason in the last six months to a year it has shifted to the idea that I signed up for a full semester's worth of courses, while still trying to work my full time job, and I'm flunking all of them because I keep going to work and never attending the classes or doing the homework.

Either way, coming up on nearly 20 years since I've been in any kind of school and my subconscious is still freaked out about it, one way or another.

By contrast, my subconscious appears to not give a flip about whether I'm doing my paying job correctly. Don't tell my boss.

Wow, seeing so many comments high school/college exam dreams do seem universal. I have had these dreams like forever. To think about high school was almost 25 years ago.

Another theme for me is not able to board on plane. More than missing flight it is about being stuck to places where I do not want to be.

Re:Geometry from Another Universe by aceazzameen on Friday January 21, 2022 @12:32AM (#30019547)
Oof. Same here. Why does this happen all these years later? High school years must have really messed a lot kids up.
Re:Geometry from Another Universe by elisaado on Thursday January 20, 2022 @07:05PM (#30017288)
It's pretty bad that school elicits such stressful responses from us that we remember and relive them 20 years later.

edit: typo.

Re:Geometry from Another Universe by FooBarWidget on Friday January 21, 2022 @04:15AM (#30021073)
I still have regular dreams about not passing high school exams. Worse: in my dreams I have to study to pass for high school exams, and work my day job, and take care of the family at the same time. Because of the commitments outside of studying, in the dream I worry about not being able to study. Then I wake up.

Maybe it is a bit more metaphorical - you just have to learn something.
Re:Geometry from Another Universe by ck45 on Thursday January 20, 2022 @02:51PM (#30013812)
This is extremely common, I googled a lot about it some years ago. I have it in two versions, the first one is that I have to repeat a maths course in school, being aware about the age difference with the other students, the other one is missing a course in university and not having graduated. The latter one feels so real that in the beginning I had to remind myself about having been at the graduation ceremony :)
Re:Geometry from Another Universe by mnadkvlb on Thursday January 20, 2022 @02:59PM (#30013904)
holy crap, i had the ‘missing a course’ nightmare roughly every 2 months for 2 years after graduating.
Re:Geometry from Another Universe by advantager on Thursday January 20, 2022 @03:54PM (#30014819)
I've had variations on this dream several times. I was talking to my father about it, and he still occasionally dreams about this. As a 67 year old, 5 years retired, 40 years after graduating...
Re:Geometry from Another Universe by machawinka on Thursday January 20, 2022 @07:22PM (#30017452)
This scares me, I don't want to be having these dreams in my 60s, do you know if there any kind of therapy? this is a bit like a mini PTSD
Re:Geometry from Another Universe by throw10920 on Thursday January 20, 2022 @03:52PM (#30014774)
I wonder why it's common? Easiest explanation would be extreme stress/mild trauma from the stress of college...
Re:Geometry from Another Universe by colordrops on Thursday January 20, 2022 @06:28PM (#30016925)
I'm guessing that it's because (at least at my university), the college class experience is pretty anonymous. No one is taking roll and won't notice if you don't show up. You sit in class as an observer, mostly quiet, almost like a disembodied ghost. The experience is already very dream like and easy to dissociate from. This in addition to the stress of the experience makes it prime dream material.
Re:Geometry from Another Universe by unsui on Thursday January 20, 2022 @04:32PM (#30015370)
I'm genuinely curious why this dream pattern seems to be quite distributed across many people.

I still regularly have the dream where I realized after graduation that I had missed an entire college class or test (often varies depending on the specific dream), but this then nullifies my graduation and all my subsequent work.

Also over 20 years ago, but still a regular visitor to my dreamscape.

Taking very liberal inspiration from the idea of something like Jungian archetypes, more along the lines of there being attractors in the informational dream-space that create narrative clusters linked to common emotions (such as anxiety), I can imagine of set of emotion-to-dream-narrative mappings that would lead to some of the regularities often seen in distributed recurring dreams:

- losing one's teeth - riding naked in the subway - being late to a class or missing a class/test entirely etc.

Just wondering if there has been any research on this that doesn't try to fall on the old standbys of Jungian archetypes, collective unconscious, and other similar handwaving

Re:Geometry from Another Universe by ballenf on Thursday January 20, 2022 @12:26PM (#30011857)
My version of that dream has me unsure where the class meets (I have a syllabus but can't decipher it somehow) and not sure if I have the right textbook for the class. I keep trying different classrooms but they all just allow me to enter without a hint of whether I'm in the right one.
Re:Geometry from Another Universe by kelseyfrog on Thursday January 20, 2022 @12:05PM (#30011587)
I have the same shared trauma response. Really does have me thinking back to my school years and trying to grapple with the two opposing feelings of "that was a lot of fun" and "gosh, why is it still giving me nightmares?"
Re:Geometry from Another Universe by skc on Thursday January 20, 2022 @05:21PM (#30016046)
My version is me running late for an exam and then frantically searching for the exam room the entire time as the clock ticks down.

The wave of relief and euphoria that overcomes me when I wake up is literally spiritual.

Re:Geometry from Another Universe by mszcz on Friday January 21, 2022 @06:24AM (#30022051)
Oh my, I'm not the only one! I occasionally have a dream that, at the end of a semester, I'm not going to pass because I forgot about some class! The realization, upon awakening, that I'm not in college anymore is wonderful ;)

I used to have this exact same dream for years after graduating from college.

Re:Geometry from Another Universe by blarg1 on Thursday January 20, 2022 @06:56PM (#30017195)
I wish someone had told me about these dreams before I went to school/uni, so I wouldn't have ever slacked off causing me to have these worries in the first place.
Re:Geometry from Another Universe by rossnordby on Thursday January 20, 2022 @06:58PM (#30017222)
If it makes you feel better, they can still happen anyway! yay!
Re:Geometry from Another Universe by jonsen on Thursday January 20, 2022 @01:47PM (#30012907)
As a student or teacher? I've had exactly this recurring dream, forgetting to teach a class. What a nightmare when they are not ready for the exam.
Re:Geometry from Another Universe by robotnikman on Thursday January 20, 2022 @05:21PM (#30016038)
For some reason this is a reoccurring dream for me as well, and its been a few years since I've taken a class.
Re:Geometry from Another Universe by jvanderbot on Thursday January 20, 2022 @01:20PM (#30012565)
I still have those dreams -- except now I know they are going to take away my degree, and thus job.

I actually had a similar type of dreams as mark_l_watson when I took quantum chemistry (that's not a drug... for most people). Since I switched to performing more mundane tasks for a living, my dreams shifted to me hopelessly trying to navigate the very real, although warped and endlessly labyrinthine, dim interior landscapes of my university's library which I last visited more than 10 years ago. It was built around 1970 and it is a kind of trip during waking hours already.

> being late to college exams while having no pants on.

The most intellectual nightmares my brain comes up with just involve demons chasing me. I've never had these intellectual dreams where there are exams, and deadlines, and being late.

I used to keep a dream diary and half of the entries were "Demons are chasing me. It is dark. I think maybe it's the xenomorph from Alien. I hear it breathing." so I stopped. Not remembering that stuff is much better it turns out haha.

Re:Geometry from Another Universe by wruza on Friday January 21, 2022 @02:35AM (#30020346)
Maybe you only remember nightmares? I have many, and they obviously stand out.

Sometimes they are funny. I had a walk in my former school district (actually I was able to jump very high and jumped around instead) and knew there are 6 humanoid monsters. But my revolver only had 5 bullets, so I had to find the armed one to take a bullet from him first.

I often have offense/defense dreams, like when I was in a room full of people, but one of them grinned at me holding a knife. I disarmed him, pushed to the pretty high window sill and carved crosses on his knees. Everyone pretended not to notice us. I hate dreams of punching someone, because my arms feel weak and slow, but when I have a gun or a "fingersniper", all enemy men become dead quickly.

I also was beaten, burning, shot, drowning, bitten, falling, stabbed. Often it's not as terrific as it sounds. Bites usually come from my recurring friend, a dog with no body, instead it's all a large mouth on legs, which can contain your entire arm. It is ~friendly.

But the worst nightmare is sort of a poltergeist. Things subtly move on their own, body gravity changes in an "intentional" way, and space becomes filled with some sort of unpleasant numbing sound. Sometimes doors don't want you to come out of them by catching my feet, I fall down and then "fall" back up paralyzed. This one is recurring from my childhood, and I (falsely) remember to experience it awake few times.

Also, lucid dreaming techniques help with detecting nightmares and turning them into something funny, or simply moving the scene far enough.

Re:Geometry from Another Universe by FpUser on Friday January 21, 2022 @03:02AM (#30020539)
I have both types. Something like what you've just described and then flying, traveling through insane and beautiful places and spaces. And it usually goes in periods. Few days of one type and then few days of the other. In between I might not see / remember nothing for a few days as well. I am 60 if it means anything.

Re:Geometry from Another Universe by mekal on Thursday January 20, 2022 @01:49PM (#30012928)
Have you read the Three-Body Problem trilogy? There's some stuff in the third book (Death's End) that sounds a lot like your dream. Specifically the different dimensions of space. If your dream didn't come from that book, perhaps you should consider writing some science fiction!
Re:Geometry from Another Universe by KronisLV on Friday January 21, 2022 @04:39AM (#30021251)
Personally, i really liked the series!

Curiously, it seemed that the books got more and more wild with each following entry: at first it was almost like "hard science fiction" with mostly feasible technologies, whereas the later books seemed to throw that idea to the wind.

That's not to say that it was a bad thing, though.

Re:Geometry from Another Universe by xelxebar on Thursday January 20, 2022 @08:29PM (#30017998)
Neat!

Every now and then I recall tripped out dreams too. In the most recent one I remember, the entire universe was a discrete regular lattice whereby neighboring points would influence the "color" of each other, very much like a network of coupled oscillators.

These couplings allowed for some Game of Life-esque life-forms to exist as locally coherent "color patches" on the lattice, of which I happened to be one.

Most of the dream happened internally to this lattice, i.e. I was not some narrator looking down at it, but frustratingly that internal experience quickly faded from memory, to be replaced by the external view which ended the dream.

Fun times!

I feel like this would have to be true in a very high dimensional space, since an infinite dimensional orange is all skin.

This sounds really fun, could you try explaining a bit more about it?

Thanks for sharing.

Huh?

As you increase the dimensionality of a sphere, an ever-increasing proportion of the sphere is within epsilon of the surface.

This 3Blue1Brown video addresses enough related stuff that the rest should become reasonably comprehensible: https://www.youtube.com/watch?v=zwAD6dRSVyI This particular result is tossed in as a side note around 23:25, so it's not addressed directly, but it'll help.

Fun facts, all major scriptures from Abrahamic religions (Jews, Christians and Islam) mentioned about multiple layers of heavens/skies where seven (7) is the top most layer. It also mentioned in the Quran [41:12] that the galaxies/stars/planets, are all residing in the lowest heaven/sky[1].

Thanks for sharing this. I love dreams like this. Flying, space travel, and alternate physics are some of the most fun. This actually makes me want to go to sleep and have a nice dream.

Does anyone know of any communities specifically for sharing awesome dreams? DreamerNews?
