I had an experience like this when I was a kid. When I was maybe five years old, I had a nightmare that I was outside my house alone in the middle of the night and saw a dog/wolf with glowing red eyes. It chased me into my back yard and eventually caught me at the foot of our toolshed. I noticed it was a German shephard and woke up just before it bit me. I woke up, no shit, at the foot of the toolshed, my head barely an inch away from the concrete near it. Scratched into the concrete was "Spike" and what I can presume was a date of death. Freaked out but not wanting to be mocked by my brother I went back into the house and went to sleep. The next morning I asked who was Spike. Spike was the previous house owner's German shephard.
I have never slept walked in my life.
