I do the same thing and I have no idea what it means. Yesterday I took a nap I thought for a couple hours but it was actually just a few minutes. Other times I sleep way longer then I think. My weighted blanket helps me. Sleepy time tea somewhat.

The store Lush makes a lotion called Sleepy. Its supposed to work very well. I used it one time and slept so much I almost had a drug like hangover when I woke up. My sleep issues are ****ed though.
