Sleep horror is were you wake up while the night and see something scary and then you can not move talk or anything it is like you are frozen in mid air. After a while it goes away and you are able to move again and you are so scared you want to do so. I have sleep horror a few people have it . It is not called sleep horror if is called sleep paralysis if you have horror dreams and they are that bad u can not move and talk. Sleep paralysis is real.
