I think this is very common and occasionally experienced by most people, including myself. Typically when you're on the border between being awake and falling asleep.
>I also sometimes get this weird perceptual thing where objects look huge, again, normally while in a dark room.
Haven't experienced this one, but perceptual distortions in a dark environment shouldn't be a concern, I think. I definitely get thrown off sometimes. It's natural, since your brain is constantly trying to predict what should be there, and ambiguous signals due to limited light can throw a wrench into that, especially if you're not habituated to the light conditions.
>I've also had odd sensations that accompany these perceptual changes.
Could there be a nocebo effect? After learning about seizure auras, it's possible that when these things happen, you might enter a brief positive feedback loop where aura-like things could psychogenically manifest. Was this also the case before you learned about such things?
Does this happen in total black ? I sometimes (really rarely, like once or twice a year) have a strange « feeling » at night while in my bed without any source of light : I can distinctively see the objects around me.
The twist is : I’m heavily myopic and even with my glasses (which I don’t wear at night) I can’t see anything in the darkness. So there is no way I could distinctly see things with their contours in the darkness.
It only happened in places I know, so I can’t know if my brain is making my bedroom up or if I really see something, or if it’s a combination.
For me it was in a dark environment (bedroom), but I was looking at my phone, without glasses, and holding it pretty close to my eyes (I'm also heavily myopic) so that it occupied maybe ~60% of my field of vision.
The "picture" I had in my field of vision never changed, the "pixels" (though I don't think there is such a thing) did not change. But suddenly my phone was this giant monolith just above my head.
Consciously I could clearly tell this was a hallucination, but the dissonance of having this seemingly suddenly huge object held right above my head was really unsettling to me, a bit scary even.
I'm so used to not questioning how my sense of scale pretty much always matches what I see, it never occurred to me my instinct could be fooled by this wide a margin while consciously seeing that everything was normal.
But on the other hand, I can't say I've really ever had an unusually distinctive awareness of objects like you describe.
I noticed while at the eye doctor when testing different lenses I guess he could recreate the feeling by using incorrect magnification on one eye? Making my brain thing the room is tilted left or right.
Unrelated, anybody ever feel like they lost consciousness for 250ms? Super rare, but I get the feeling that I feel asleep and all my muscles went limp in that moment. It's like when you are falling asleep and you sometimes jerk yourself back awake.

I thought I was going crazy for a while until I found out what it was.
Every once in a while, i'll have this and there's an entity in my room. Once, everything in my room flew and the world 'cracked'. It's just a waking dream. Wiggle your toes, and things will go back to normal. Toes still work when the delusion sets in because it takes time for the hormone that causes bodily paralysis to get to your toes, and when the brain notices you moving your body, it wakes back up.

All of these occur very rarely. Like I said, maybe twice a year, but closer to once per year. I can't find it now, but I had learned about seizure activity and how you can experience one without really knowing it, things just might get wonky like your perception, feelings, smells, etc.
