I have this recurring thing where I notice things like this when I’m dreaming, and it causes me to wake up in the middle of the night. Except I didn’t wake up. I dreamt that I woke up. Then I often fall back asleep again. I don’t wake up until something’s strong enough to wake me up twice.

Except sometimes when my body really doesn’t want to be awake, I’ll wake up a second time, then a third, then a fourth, and it just goes on forever until I’ve really overslept.
