Imagine if you started hallucinating naked people. That would be best.
Like lemon party, right? I hope that doesn't slip into OP's hallucinations.
OT: Well, not any that I remember but apparently I was little I have been sleepwalking for a short time and talking nonsense. My mother told me I once went to her and told her I couldn't sleep and a string of other words which didn't make much sense, so she led me to bed and I only learned of that in the morning.
But a friend of mine, smoked some weed but behaved properly for a while until he suddenly froze mid conversation staring behind me. I turned and there was nothing there - just the door to the hallway, but he was convinced he saw a ninja walk past. I tried to tell him that it was impossible but he wouldn't take it. Finally, I walked in the hallway and pointed out that if there was a ninja in the house I would have been dead already. That calmed him down.
A different friend of mine smoked some shisha. It even had normal tobacco in it (taken from a cigarette) but somehow it hit him hard. In about half an hour he was lying on the sofa barely moving, not talking and wheezing. We asked him if he was OK but he only managed to whisper faintly "It doesn't allow me. It doesn't allow me to breathe. The shisha.". True story that one.
