My brain, I swear.

I woke up at about five this morning. I swear that I heard the door open and close and a man call, "hello?" I was fairly certain that no one had come in? And yet, if I didn't check, I knew I would not be able to go back to sleep.

So I got up to check.

Yeah, just my imagination. I answered the call of my bladder and then went back to bed.
