I often wake early in the mornings after just a couple or three hours sleep, and then of course my brain races to bad places. I HAVE to get up out of a 'bed', and ground myself with games on my laptop or Facebook. or whatever...or, in today's case, coming to this site for comfort. I make coffee and go about things as though I've had a great night's sleep, Invariably, I get very sleepy again and lay down on the sofa for a little snooze....which sometimes lasts several hours. For me, something about not being in a 'bed' helps me feel safer. The back of the sofa is behind me, and I keep a little lap blanket there to toss over myself...or just clutch close to my face.
