dream of cross-indexed climbing

I was staying in a dorm-like cottage at the base of a rocky mountain, and everyone had to have licensing information to be able to climb upward. My father was there, I think, but I never realized why. It was wonderfully green around the dorms and the sunlight was diffuse. I kept searching through huge bookcases to find the letters that would allow me to go up and out, but they weren’t there. I woke up before I found anything.
