Dreaming about sleep

A first happened to me last night. As I was sleeping, I dreamed about being tired and wanting to go to bed. I only mention this because this seems an odd thing to dream about when you are already sleeping!!

I wonder what this means??? They say that you dream about things that you need or are subliminally thinking about. Could be it be that I have a subliminal obsession with sleeping??

The odd thing is that I wasn’t even that tired when I went to sleep!!
