Its 12:38 in the AM, another sleepless night. This happens  a lot, getting up checking doors etc. Head explosions happen quite a bit, head explosions are when you are asleep and a loud crash, or boom startles you awake only to find nothing happened, its all in your head. There is a clinicle name for it but I don't remember what.

My adopted mom used to wake me up to watch her play solitaire in the middle of the night, she would make me stand up while she sat and played, I often fell asleep only to awaken when I hit the ground, it was torture at best.
