Is it normal to do this?

When I'm laying in bed at night trying to sleep, my thoughts are pretty constant. Normally, they don't end until I find some sort of solution to the problem or situation my mind is thinking about.

Recently, I've been putting someone else into the thought process in my mind. So there's me, and another person, I guess me also. I don't INTENTIONALLY have these conversations but when my mind goes on a roll about something, it throws in another person to keep it going. I have only recently noticed.

It's always someone that I feel I should say the things that I think to. I feel like it sounds weird. but I also feel like it's a way to sort of cope with what goes through my mind.
