I was dreaming that I was climbing up various flights of stairs. I then reached a brightly-illuminated floor, and I tried to get across it, but it had aisleways blocking my path across. I tried to go back down the stairs, but it was dark, and for some reason I was not able to. Then I dreamt that I was at a department store, and I was about to leave through the revolving door, but it was as if I were frozen, and could not move through the door. At this point I woke up.
