All the dreams i ever had i've died.even ever since i was a child.why?

I hadve a long line of dreams where i die in the end.unfoutunantly i die in all my dreams.not one have i lived.heres a few of them in no particular order.there was the one where i was eaten alive by spiders, locked in a cage with a serial killer, falling off a roof, falling off a cliff, falling off a roof in slow motion, (that was a dream i had at leat 5 times) there was the alien invasion, the fight at school with a mutant, chubaca, there was the angry stampede of black ghetto children, once i was sucked to death in a tub full of leeches, once i had my nuts cut off and i bled to death, once i learned how to fly and i flew into a tree, the tree was in the sky i fell (in slow motion as usual) then one of my stuffed animals came to life turned into a monster and killed me, there was the one where i fell into a bottomles pit, the one where i was dragged to hell and burned to death, and then there was the one where i was standing in the middle of no where and just dropped dead for no particular reason.yup thats just a few of the dreams i've had.how do i make them stop.why am i having these dreams.i mean they used to be scary but now there just there.but still is something wrong with me.
