I dream of dead people.....often...help

My husband keeps telling me I should sell my dreams to Hollywood for a scary movie! Basically I dream of people I know who have passed, they usually talk to me. When I wake I take into serious consideration what they've said. But sometimes, I'd say a handful of times, I have dreams that I am watching a murder take place. From who is doing it, who is being murdered, the location, and what happens after.......its really creapy and I'd prefer not to dream this stuff. I sometimes wonder if someone from the other side is trying to contact me to help them solve there own unsolved mystery. Am I crazy???
I find these awfully scary dreams happen only when I do something different in my room then I normally do, such as, leave a light on, or forget to open the window, besides that it always happens when I am laying flat on my back, I always feel exposed and uncomfortable when I wake up so I make it an effort to sleep on my belly to avoid all of this. Not last night though.
Last night, my humidifier was turned on high instead of low, the heater was cranked up to about 80 degrees, neither the door or window was open, and my husband moved the doggie bed to his side of the bed, plus i was flat as a bored on my back.
I dreamt I was either this really tall overwieght Caucasian man, or that I was watching him. He was in a small room with two Oriental men, father and son. The father was laying flat on his back on a cot of some sort and the son was sitting on it down by his feet. The Caucasian came in swiftly with a huge butcher knife and started to chop the fathers stomach in half, he then made a swing at his throat to finish the job. He was going to start on teh son now, but was so grossed out by his own murder all he could do was swing at the sons arm making a small cut, dropped the knife and ran!!!!!!! He ran through the mall, circling around a group of babies, then following a rich Paris Hilton type. I'm guessing that a few weeks had passed cuz in the mall he passed the son of the father, but the son didnt recognize him! Regardless of this, he ran anyway to the parking lot where his huge van with strips painted on it was being jumped by his good friend. While they were jumping it, his friends finger got cut off by accident, this triggered something in the Caucasian man. He started screaming and ran for his life as far as he could. Of course his friend thougth it was funny so he chased him holding his finger as close as he could to him. But then his friend thought he was overreating more then he should, so he asked him "You did it didnt you? You murdered him!" And the man said yes. So his friend beat the crap outta him, so much his face swelled like a ballon.
That's the end of my dream, doesnt sound that scary now, but being in the dream watching it first hand was gross. What do you all think about this dream? My other dreams are just the same. I've had dreams of dead people on a Subway, teenage girls being kidnapped and killed, etc. Why me?!
