I took mushrooms once, it was fun. Things were more interesting than normal and after a while, I just listened to the conversations around me, cause I couldn't concentrate on anything and couldn't even look at my phone or hold stuff, cause my hands were feeling weird. I think it stayed on my system for a few hours, but the "big" effects lasted one hour tops. I did take a very small dose, since I'm not that used to drugs (weed and a beer less than once a month). My friends also had never taken mushrooms before, so everyone took small doses, and no one had an actual hallucination lol.

Don't recommend people doing it for the first time without people you trust, because you get really vulnerable. 09/10, would do it again. Do NOT take hallucinogens if you have a history of schizophrenia in the family.
