This would have been the perfect opportunity for you to become lucid in your dream. I cant easily become lucid, but typically if i am having a very horrifying dream, your mind recognizes that you are in a dream, and typically choose to wake up. Instead of actually waking up, recognize that you are dreaming, and continue with the dream! Another reason this would be particularly effective with this dream, is that there is a technique of determining if you are dreaming. If you are not sure if you are dreaming, try to turn on/off a light switch. If you are in fact dreaming, the light switch will have no effect on the current luminosity.
Neat personal story about lucid dreaming.
My school's performing arts building is across the street from the main campus. Now there's a walk way where the students have the right of way all the time and the cars stop, but that doesn't always happen, and infact I was almost hit by a car that didn't stop. So anyways, in my dream, I'm walking to class, when all of a sudden, my feet just don't work, I'm rooted in place in the middle of the street, while a semi is barreling down on me, and all my friends are yelling at me to move. One of my friends was a kid I hadn't seen in forever, and that's when I realized it was a dream, and instead of waking myself up, I started lucid dreaming again, and my feet could move. But I stayed there, and let the tanker pass through me. It was a phenomenally odd experience, because I could feel the gas being wet and the engine being warm, and all that stuff, like some one sent you through a quiznos grill then doused you with water in about 1 second. After that I started to fly around and stuff, get a bird's eye view of what was going on, but my body was still there in the middle of the street. It was pretty weird.
Regarding recurring dreams: I used to have one when I was a kid, like 8-10ish, and thank God I don't get it anymore, cause it supremely freaked me out. Basically the dream was one where I am walking up to an old like Louisiana Bayou shack with a pristine white picket fence. I'd walk through the gate, and then everything would turn to white, and blue balls would start falling all around me, the ground would shift, and I couldn't keep my footing. Finally after this went on for what seemed like 20 minutes in the dream, I'd see an opening, and make a mad dash for it, but I'd have to crawl through it, and once I got like half way through It would close up, and kill me.
At that point I either woke up or didn't, it seem like it was about 50/50. If I didn't wake up, I was instantly transported to this place above and to the right of my body, looking down on it, and it was DEATHLY cold. And all I could do was look at it.
That dream freaked me out so damn bad, and I had it at least once every 1 month for a good year or so. One week I had it twice in a row, and was in tears in the morning when my mom woke me up to go to school
