i absolutely have. whenever i smoke a lot or really good bud i do....like the trees or stars will become faces..ususally just minor stuff like that. one time though i smoked this joint of weed i bought at Cornell University. Everything was fine except my eyes wouldn't stop being red. They were like beet red for hours and i had no idea why (at that time they never STAYED red for that long). well like 30 minutes after smoking i was looking at my friend and his face just started to shift. it changed. he began looking like movie stars and people ive seen before. it was SOOO cool. it just kind of melted into someone else, but still his face, like you could tell. it was so good.

later after much deduction i guessed that someone had put their weed in the same bag as their shrooms and it had some spores on it or something. either way it ruled.
