I managed to have a good sleep last night. I went to bed about 1am and think I slept soon after that. Dreamt quite deeply. Past relationships all merging into one continuous timeline. Also all locations were seamlessly attached to one another. I felt much better today. Pre-dose butterflies are still there. The tube strike has been called off, which would have just caused a complete nightmare for me getting to the hospital. Robin has kindly arranged that I can stay at the hospital accommodation overnight to avoid the toxic soul-death of rush-hour tube travel. I'm not looking at any more videos now related to Psilocybin.
I keep thinking of how nice the setting and music were. It really did help doing a "dry run" of the set and setting. I think I would have been more nervous if we hadn't done that. I'm going to take my own earphones as the ones there kept falling out when I tried them. I'm still quite tired today.
