Yeah, some of the characters in my dream exist beyond the situational scenerios I create in my dream so they can pop up and do whatever they wish.

One example is Coach McGurt from the show home movies. Before I was able to go lucid he used to be in every one of my dreams. Now he's just a character that walks around until two weeks ago when was about to run a crazy experiment.

Basically I was playing him in a game of chess and if he won he would get to take control of my body when I awoke. I didn't know what would happen but I decided to will myself into winning and not experiment with myself in such ways. I locked him away in prison which when I first went their found that a whole bunch of the evil villians I fought for fun was there. I guess that came to be because of my intrigue in the home of infinite loosers from DBZ.
