Seeing things.

You know the moment when, after spending over an hour up in the middle of the night with a small child, you finally get them tucked in, and you’re walking towards the bedroom? When you know that, while the house is mostly clean, there’s still a good chance of a lego or doll or toy that talks to be directly in your path and you must walk carefully? That moment when you’re seeing spots, you squint, blink, trying to get your sleepy eyes (that aren’t wearing prescription correction, of course) to adjust and the spots the clear? You blink, squint, and realize that’s just making the spots bigger. And then, half a second before the spot is going to hit you in the face, you realize it’s a floating balloon?

Yeah, that’s never happened to me, either.
