Seen a couple.........First when I was 9, was horrified. It was standing on my parents bed and beckened me to come to it. Later on I think it was sleep paralaysis. Just horrified. Then when I was depressed I felt and thought it was really really real. I was tucked in with my covers and felt GREAT love. Like it was saying. I LOVE YOU AND THAT'S ALL YOU NEED IS ME. Sounds freaky. But it felt so real that I wrote it down in a diary. Talked to people who saw people who had died. Don't believe that it was who they thought they were. Satan also can change into an angel of light you know. See'r beware.
