I've tried DMT. It was overwhelming. I was a baby in a huge crib. Everything was covered in the same texture, red and black stripes, slowly crawling over every surface.
At each corner of the bed was a robed figure wearing a Mickey Mouse mascot head with a pointed, conical cap like a party hat. They said nothing, just studied me for a while until I returned to reality.
Wow, sounds like DMT alright... It's interesting you encountered Mickey Mouse imagery because I had Goofy appear in my mind's eye after blasting off once.
