What do you think of right before you fall asleep?

Depends on my mood.. If I'm stressed, really tired, etc

Usually I'm thinking of a series I watched, and imagine myself as a main character lol
Or main character of a book I read before, in hopes that I will have a dream about it.

When I'm stressed I'm thinking about how little time I have until I have to get up, or how many things I have to do next day, or I'm rethinking what happened

How little time I have left before having to get up again.

Secs

When's breakfast?

I think of my son
