Like Papa said, first I've heard about it. But, it's funny. I do about that same thing.

Being retired with few scheduled appointments . I sleep when ever.

But it's quite common for me to sleep a few hours starting about Ten PM then awaken around Two AM then sleep again around Five AM again to finally awake around 9:00

Interesting
