Waking game

the waking game is: you fall asleep in an unusual location and on waking up try to recollect where you are.
Yesterday I fell asleep at the office while typing smth on the computer. Then I wake up. I open my eyes, see the keyboard, don't recognize it, see the room, don't understand, where I am. Worse: I don't remember, who I am.  Panic! Just one thought in my mind: if I realize where, I'll recollect who. Slowly, like a computer restoring the system, consciousness returns: it's my office - then I am such and such... For a few moments my brain was absolutely blank. Perhaps, this is what crazy people feel all the time: fear and total disorientation.
