pre-sleep 

A late-night accidental nap in a chair or on a sofa, in which immediately upon waking up one goes to bed for the night.

I guess I dozed off into a pre-sleep while watching tv. I was really disoriented when I woke up from that, but then had like seven hours of amazing sleep.

presleep 

Falling asleep in front of the TV long before bedtime, usually the best quality sleep.

"Where's Chuck?"

"Oh, he's presleeping in front of the news again."

Similar to resleep (trying to fall back to sleep after being wakened unnecessarily). Also similar to desleep (being awakened unnecessarily).
