I haven't done mushrooms since once at college. There's a funny story about that time.

There was an annual organized trip to Disneyland at my school, and a large fraction of the student body went. I decided not to go that year, and picked that night to try mushrooms because the campus would be sparsely populated. I figured that the fewer people there were around, the fewer chances there were for something to go wrong.

I had done a lot of reading, and talked to a lot of people who had used them, so that I knew what to expect on a mushroom trip. I was seeing and feeling the effects I expected, and having a good time.

Then several people I did not recognize walked by, speaking Chinese! Then more Chinese speaking people walked by. That was weird. I started wandering around campus, and kept running into people I did not recognize who were speaking Chinese.

This was very unusual. My school (Caltech) was small enough that every student could normally recognize every other student by sight, so seeing so many strangers was odd enough...but that they were all speaking Chinese was just freaky.

Nothing I had read or heard said that mushrooms could make one have that kind of hallucination, so I was starting to get seriously worried that I was on more than just mushrooms.

It turned out that I was not hallucinating. I had not been the only one who decided to take advantage of most Caltech students going to Disneyland that night. The Chinese Students Association picked that night to throw a party and invite the Chinese students from UCLA and USC and nearly every other college in the Los Angeles area.
