This is a nice overview of paradoxical insomnia, which is when people swear they’re staying awake much of the night, but they’re actually just in dream states that are so real they feel they’re awake. It also offers some ways to work with this perceived (but not real) lack of sleep.
But here’s the twist: Whenever my partner stirs and looks over, he swears that I am actually asleep. My eyes are closed, I’m breathing slowly—sometimes I’m even snoring. I never believed him but that posed a question as ridiculous as it was eerie: Was I awake or was I asleep? And how, come to think of it, are we really supposed to know the difference?
