Last night I could tell I was 1/2 a sleep and 1/2 awake, you know when you have the first little dreams before you fall asleep?
As soon as I relaxed, I heard 2 loud screams. I woke up scared and looked around and at my wife beside me, and she was sound asleep. My folks were asleep also. I know this may sound funny but I had a scary feeling in me that I covered myself with the covers like a 5 year old.
What does that mean? Was I having a dream, or how can it be explained?

Any answer would be appreciated
