Something Gruesome

The other night I had a horrible dream...
My father was murdered while staying in a mansion hotel for business. My gut told me it had been the act of a serial killer. My mother and I were called upon to view the damage, per say. When we got there it was late at night. The hotel manager lead us into my fathers room where his body was dismembered and hung tangled from a ceiling high four poster bed.
Flash...
For some reason my mom and I had three cars with us. To make sure we were not caught by the serial killer we checked to make sure none of the lights were on in the cars and we had all the keys. It was raining when we went outside to do this; your typical horror film plot.
Flash...
On the roof of the hotel, at the skylight above my father's four poster bed, a man is peering in. With a flat hand he hits the skylight once.
Flash...
I'm inside the hotel room alone. Directly after the man hit the skylight, tons of money fell from the ceiling as though resting on the skylight on the roof then suddenly falling on the inside.
Flash...
the money is gone.
Flash...
Later, which felt like the same night and the next day, when Hotel staff and forensics had cleaned up my dad's body my mother and I viewed the hotel room once more. Again, we were accompanied by the hotel manager. There were blood stains still on the sheets.
I woke up sickened.
This, in summation is the entirety of my dream. It was very unsettling and aweful. I never have dreams like this!!
I've had one other dream before where my father died when I was probably twelve years old. However, instead of being heartbreaking, gruesome, and unsettling, it was deep, sorrowful, and peaceful.
I entered into a white decorated room. It also had a four poster bed. There were red rose petals sprinkled across the bedding. This was supposed to be my father's room when he was alive. The room was musty and light reflected off of dust in the air. I walked to the bed side and my father's spirit appeared. He was there to say goodbye and that he loved me. I cried...I woke up crying.
Why did I have these dreams about my father dieing?
He is so important in my life, I love him so much. These dreams reflect one of my worst fears. I hate them.
In Waking Life, at the beginning of the film, the little girl with the fortune teller stated, "dream is destiny." I suppose it is everyone's destiny to die, but to see my father's death so blatantly displayed in a dream is not on my agenda.
I found out the next day when telling my mom about my dream that she had had a horrible dream too. She was with her two children, who didn't look like my brother or I, and they found a dismembered body in the bathtub. When trying to shove it into a plastic bag her son somehow accidentally ended up in the bag temporarily with the body.
My mom has not watched a horror movie in years!!
She has never had a dream that aweful!!
We had it on the same night and both woke up from them at five o'clock in the morning!!
What do connections like this mean?
I hear of books that tell you what your dreams mean. I wonder what they would say about what my mom and I experienced?
