alt Hacker NewsI once spoke with a family member who was experiencing hallucinations of little people at the moment. So I guess if you want to experience this at home you can try giving yourself a head wound. Not as active or vivid as described I think though, they just said that the little people were hanging out up in curtains peering at us.
That reminded me. Almost 20 years ago, there was a city folktale that some species of Convolvulus could get you high, and my friend tried it and then described seeing little knights playing|fighting on a wallpaper. I was a designated spotter, and didn't know what to do, so I just wrote down everything she said. Still should have a notebook somewhere.
(It was 2 specific species out of 200, and I hope that not mentioning which part of the plant she ingested would deter people from trying. The plant is also slightly poisonous, could weaken your kidneys. Weak kidneys no fun)
