I have also done this since I was a child, glad to see its not just me! I have several story lines running at any given time, and will daydream about them depending on my mood.

Does anyone else get sad when you can't get back to a certain story in your head that you used to love? Like you remember the details but it doesn't feel real anymore? It probably shouldn't be something to mourn, but sometimes I miss the way a certain daydream would make me feel.
