Dream or Nightmare?

Ok I know the answer, this was strange or something, but. I had the worst dream/nightmare that I can remember ever having. I woke up at 5ish this morning (I'd like to add that this was the 1st night that I didn't wake up at 3am to check on the dog/s - I have continued to do this even though Sophie is gone & Simon is fine)

I woke up my heart racing, breathing heavy, adrenaline REALLY pumping. I had a dream that a man busted through our front door & was using me a "baseball bat" to open doors. In my dream I managed to scream to Lsquare to call 911. After that my speech was paralyzed I couldn't speak no matter how hard or loud it was in my mind. Nothing came out. I was trying to fight this guy off, but couldn't I was like a 3 year old trying to beat up an NFL player. It was no use, he would pick me up & throw me. All the while I was trying to speak & couldn't. I finally yelled something out that this guy had killed someone, but who?

I then was wide awake, remembering every detail, like it had actually happened. Out of breath, heart racing & feeling the adrenaline really going to town.
No I didn't watch anything on TV or the news, ( i don't watch suspense stuff) we weren't home to watch tv & when I did turn it on it was Late night with Conan sp?.
So I'm left somewhat spooked by this & feeling like I have been in a car wreck (I've been in a few) my whole body is stiff & aches. I'm so tired but somewhat fearful of trying to sleep.

So I welcome your thoughts.
