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)
