I’ve never heard of “D” but I know from experience actual proper LSD is not to be taken lightly either.

D = DMT

For sure, One should respect LSD also. It is not a 'party drug'. But DMT is something quite different. LSD will warp reality for a day. D will rip you right out of reality for 5 mins.

Comedy Central runs a Youtube series where comedians talk about their drug trips, and the DMT ones always seem INTENSE. It seems like if you take enough you basically check out of reality for a while, wondering if that's true/what your experience was?

Literally ripped out of reality. Teleported to another time and place. It totally disrupts your senses from reality, and substitutes something else. One time I recall seeing the walls growing with vines like snakes, and being transported to a place with purple light.

When you emerge, you feel refreshed and renewed.

Do you remember deep dream? When i first saw it, I thought we might have some kind of ML model of the human experience of D.

I also had that purple light vision. Curious if it was the same? Mine was our in space, purple and white lights all over the place, some kind of universal womb with souls.

I wonder if that connects at all to the pink beam of light that Philip K. Dick wrote about in VALIS, etc https://en.wikipedia.org/wiki/Valis_(novel)
