Last 2 experiences of high dose mdma.._1) got home after a night out and carried on dosing in my room. Had a really long conversation with my mate who was sat next to me. Started to sober up a little and realised my mate wasnt there and id been talking to my lampshade. 2) went for a walk in the woods after a night of smashing MD indoors. Stopped for a piss in a bush and when i was done i looked at my mate stood next to another bush and said " cmon are you coming?". Again, nobody there , so i walked home lol
