I woke up as the sun was reddening; and that was the one distinct time 
in my life, the strangest moment of all, when I didn’t know who I was - I
 was far away from home, haunted and tired with travel, in a cheap hotel
 room I’d never seen, hearing the hiss of steam outside, and the creak 
of the old wood of the hotel, and footsteps upstairs, and all the sad 
sounds, and I looked at the cracked high ceiling and really didn’t know 
who I was for about fifteen strange seconds. I wasn’t scared; I was just
 somebody else, some stranger, and my whole life was a haunted life, the
 life of a ghost.
Jack Kerouac, On The Road
