Dreams.........

I'm a totally different person when I dream. A lot of the times I am so angry I end up fighting someone and always feel like I'm the only one left out. Or there's a huge disaster and I'm the only one who can fix it. I've had my children kidnapped, die on me, reseen people who have past away............all in my dreams. What are dreams really? Just some thoughts I've been having. And does this mean I want to be a violent person o already am?....No to the second :)
