Strange Dream

I just had to write a quick post about a dream I had last night. It was really strange and like most of my dreams since becoming pregnant, very vivid.
I dreamed that I was riding in a car with LaVar Burton, the guy from Star Trek: The Next Generation and Reading Rainbow. We had a really nice chat and before I got out of the car he gave me an autograph for Glenn and I to share and another for my brother, Eric.
I have no idea where this dream came from. I can usually find something that I read or watched that put ideas into my head but this?
