Sleep (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the turn into a world of one's own; waking is sharing a single, common world.

Sleep (n.) sorts ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠beings for Heidegger: the stone neither sleeps nor wakes, the plant's sleep is doubtful, and the animal sleeps — but is it man's sleep?

Sleep (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a binding — a desmos, a way perception is tied up — not a matter of consciousness or unconsciousness.

Sleep (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠not a lapse of consciousness but, as Aristotle saw, a binding — a way our essence is held so that it cannot take in other beings.

Sleep (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a question about what kind of being something is: we never say a stone sleeps, are unsure whether a plant does, and know the animal does — without knowing if its sleep is ours.
