Nights in limbo and puzzling mornings

Is there a name for that sleepless sleep where you feel you're stuck in limbo, not really sure whether you've slept or stayed up throughout the night?

When you don't remember if you actually dreamt or thought up scenarios the whole night through just so you could sleep. 

When each time you opened your eyes to realize it's not time to wake up yet, and shut them again so you could tell your body you're sleeping.

When you remember each toss and turn, each huddle for cozier spots under your duvet, and each time you stretched out your hand for a quick sip of water. 

 It's limbo alright, because you don't wake up feeling dead, your legs aren't aching from lack of sleep, your face feels fresh and yet you know somewhere inside you hardly slept..or maybe you did.  How can you tell? Awake at 7:00am and still shutting out the morning light, eyelids are a flimsy curtain though, and yet you shut them hard, for an hour but it's only been five minutes and you're out of bed. 

 Puzzle yourself hard, you remember the entire night and yet maybe you slept somewhere, maybe in your mind. 

 What did I do the entire night? Ah, I kept running some voices, some faces, images and words. Lines and poems, and stories of space slatterns and mercenaries. Of rhymes that rhymed and ones that didn't, and prose and verse and letters unwritten.
