Boy, did I sleep in.
I woke at the ungodly hour of 4:30, used the necessary, and laid (lay?) awake for two hours! But I was determined to get back to sleep for a bit, and I did indeed, and I nearly made up those two hours.
The result, though, in a case like that, is the incredible dreams I have in that “extra” sleep, and this one was a doozy.
