The sleep of reason

"Common images are bearded, goblin-like demons laughing or whispering sinister speech, a faceless girl (usually covering her face with hair, moving around in bed moaning and feeling my body), hands appearing from the wall and attempting to strangle me. A hung man talking in the corner of the room, and some of the most bizarre experiences may include up to a dozen 'critter' entities (think Gremlins movie) laughing and talking about me. The environment tends to feel like a holographic dollhouse, the experience peaks and then the hallucinations mysteriously vanish when I regain control of my body."- The bizarre world of sleep paralysis, a form of hypnagogia and root of many folkloric figures such as succubi or incubi and the night hag.

What 'x' are you?, where x=sleep type

Foetus, log, yearner, soldier, freefaller or starfish? And note that the percentages only add up to 89%, which either means that 11% of us are vampires that hang upside down from our ankles, or there's more ways of sleeping than I was aware of.
