I was standing in a place like an old park I used to visit, which looked completely different, walking around with ghosts behind me and bare-foot over sharp rocks (which didn't hurt at all), when I suddenly walked through a doorway in to a library. I use doorways as a reminder to RC, so I tried to push my finger through my hand to see if I was dreaming. My hand was solid, and it didn't go through, so I thought it was real.
The ghosts confirmed my suspicion and told me it was real.
I woke up and punched myself hard.
