How do you make pictures in your head with your eyes closed, i try to visualize but i can never see anything except one time when i wasn't trying to visualize. One time i was watching this show about big foot and then when i closed my eyes and was trying to sleep (but wasn't asleep) there was this picture of big foot in my mind with a white line around his body and black fur inside and he was flexing his muscles. I didn't do that voluntarely though.
