i've hallucinated on it before. but i was also high off my ass which could of caused it. and its only happened once. it was pretty trippy. i saw a random guy in the corner which wasn't there then i saw a spider on the floor which turned into a lot of spiders. I decided after that it was def bed time lol. but i have heard stories from other people hallucinating on it.
On ecstasy once I hallucinated a tiger run up my arm and it looked at me and it had the face of a woman I knew and smiled , then she started cleaning herself like a cat lol. I highly doubt that was MDMA doing that but those were quality pills lol !
