Something looking different in size than the previous day

This morning, while I was taking a shower, I looked at the long-handled poof holder that I use to wash my body. For some reason, the handle looked shorter than it looked the day before, but obviously it didn't shrink. So, it was just my brain! I just sort of shrugged it off. I just try to have a positive attitude and hope for the best. In thinking about this, I wonder if the fog rolled in briefly.
