I used to have very vivid horrifying nightmares. Not so much anymore though. I've described my dreams to a couple of my friends that are into magick and such, and they're so detailed and vivid, my friends believe I might've accessed the astral plane, lol.
What I really hate is when I have a horrible nightmare, and in the nightmare wake up, but actually go right into another nightmare. Has this happened to anyone else? When I actually did wake up I was terrified to get out of bed, because I didn't know if I was awake or dreaming.
There have also been a couple dreams that were so real that for awhile I forget they were dreams and think they really happen, and then I realize later they were dreams. Like once in seventh grade, I had a dream I yelled at my teacher, and when I went to class the next day, I was trying to remember if I dreamed it or if it really happened, but I could tell by the way she was acting it must've been just a dream.
Oh! I sleep talk too. And not just sleep mumble, like people can understand every word. Apparantly I've really creeped people out with things I've said in my sleep. o_0
