It's weird how the mind creates dreams. 

The other day I was reading a book, and my dream that night expanded on the topic I read about in the book.  It was weird because the topic was mentioned almost in passing, but my mind seemed to take it and run with it.  I awoke wondering how those thoughts got it my head in the first place, then realize it must've started with the book. 

Even more recently, I dreamt that I was mad at someone, and when I awoke, I felt the same way and had to convince myself that my feelings were based entirely on a dream.  It was exactly like this Brevity comic from last week. #psychology
