One time, while attempting to exit a parking garage, I became frustrated because I couldn't find where the "down"-stairs were.
Interestingly enough, I was standing right next to a staircase leading to the lower level, but for some reason my brain was telling me
"No. You can't go down those stairs! That stairway is for people trying to come up to this level."
(stairs==escalators??)... So I stood there for longer than I care to admit, until I finally realized that stairs aren't one way, and I could easily manage walking down them.
