I need a word that goes in between the brackets: "the  of sleep." I don't want a generic adjective, I want something that conveys the emptiness or otherworldliness of sleep. You know that moment when the dreamworld evaporates and your epistemic grounding shatters. The moment when you just realize that you are truly awake and reflexively try to unscramble your recent memories from reality. That's the kind of thing I'm looking for. It could be a phrase as well. But I'm certain it's there. Ideas?
