Small doses. Never enough to disassociate. Only lots of LSD and 4-HO-DET ever did that to me.
The most striking memory with DMT was at night seeing a moonlight cloud full of skulls staring back down at me. I frequently saw skulls in any texture.
It was very long ago. Unfortunately the dealer was raided.
It left a noticable residue in the simplistic vape we had and a few subsequent uses still carried traces of it.
