You were scared to fall back asleep, hence <Nightmare>
Let's see...I remember back when I was like 10 or 11 and I was into Goosebumps then. I remember reading this book about this evil dog with red eyes. I forgot what the book was called, but the dog was evil. So after some time of reading that book, guess what?
I had a dream that an evil dog with glaring red eyes was attacking me. And I even remember waking up screaming and thrashing my feet. Ever since then, I slept with my frog

(stuffed animal) and since then I never had any bad dreams. I never went to sleep without it. I got out of that habit eventually,

, around 15 or 16

(I had to move on one of these days....)
So once I got rid of the frog, I realized that I would have to face the nightmares eventually. I remember one time I had this dream about being in a tunnel and this ghostly figure shaped demon was after me. I think he even grabbed me, but I escaped his grip and I woke up scared to death. I couldn't fall asleep after that. Everytime I closed my eyes, I would see the image and open them again. I remember staring at the ceiling with my eyes wide open. I couldn't do anything but gaze at the ceiling. I didn't want to fall asleep again.
There as been some more, but I can't remember them right now. But those two stick in my mind forever.
Anyways...how about you?
