Many years ago I recall realizing, while tripping on acid and mescaline, that the snakes in my bed were merely hallucinations which, if embraced, would be harmless. I found they became quite gentle when stroked, and I continued to do so for what seemed like hours, all the while wishing they would not wriggle about quite so much. A flash of lightning and very loud clap of thunder made them disappear from my view, and drew me to the window where I quickly became engrossed in the lightning show produced by an approaching thunderstorm. When the electric show finally became obscured by driving rain, I was able to leave the window an look for my friends the snakes... but they had apparently let themselves out while I was preoccupied with the lightning show. The rest of the night was spent in the laborious descent into the depths of a geode, and the even more laborious climb back out of the rock, which I thought I had to accomplish before I came down, otherwise I might be trapped in that rock.
I still have the geode, but I've not seen any of those snakes since that night.
