Dream Walker

I wonder if it is possible to visit other people in their dreams. That maybe when they are dreaming about that is where you are. I am wondering this because I have been told a lot this month that I have been in someone's dream.

It all started when my Anatomy and Physiology teacher told me that I was in her dream the night before. She couldn't remember why just that I was in it. Then two deferent managers at work had a dream with me in it and a few of my friends.

It is weird to me because I have not done anything outstanding lately for or around any of these people lately... Or nothing really bad either.

Maybe I have been dream walking.
