One time I took a long, deep nap after school and didn't wake up until 7-ish PM. My dad came in to announce that dinner was ready, but I kept insisting that it was 7 *AM* and that I was going to be late for school (which started at 7:20). He kept telling me that it was nighttime, but I didn't believe him. We really had an argument back and forth whether it was day or night.

In the end, I think I just finished my nap.
