I don’t typically think of weed as a psychedelic, but that would have been the first substance I introduced to my body. Hash actually. I was 15 smoking out of an apple. My buddy and I “went to bed” for the night one evening and went to my room. He was crashing at my place for the weekend.

After about 30 minutes I looked at my wall which had a sponge textured paint on it, and the sponge prints sorta turned into these buffalo looking things rocking back and forth. This caused me to laugh and then get paranoid my parents heard us. So we put it all away and went to bed.
