This isn't a dream per say, but when I was in about, oh, fifth grade I was watching an old TV show called " In search of". It was hosted by Leonard Nimoy (of "Spock" fame) and would talk about strange occurences (you know Ghosts, Yetis, Loch Ness monster, standard stuff). So one morning I'm watching an episode about ghosts in English castles. Some lady apparently was frightened to death by a ghost. So it shows her going to bed with the ominous music playing. Now I was getting slightly creeped out, and I happened to turn away for some random reason. Now then I look back around and the most disturbing, hair-raising apparition I have ever seen is staring back at me from the TV screen. I about had a heart attack and had to watch several episodes of the Smurfs to stop shaking. Slept with the light on for several months afterward. To this day, I never found out exactly what that thing was.
