Why are my dreams so weird?

Well my dreams are really weird.EXAMPLES: in one of my dreams my next door neighbores dad was chasing me with a nife that we have in our kitchen that was crooked, and also i had a dream that i was in my house and there was a party and then the party people kicked me out and i ran to my friends house because it was like 10 at night and then i looked close and i saw a big white unicorn with two huge white swans and two huge white cougars, and they were nice. they a big white beautiful tiger came to me and let me get on his back and he took me home in my front yard and lay with me until my parents came home, there were many more white big animals to. and one more, i was being chased by devilish creatures ( before i went to bed the night before my mother told me to say in the blood of god ) and i screamed in the blood of god and then this huge white angel came to me and told me to hug him/her and i did and i woke up????? so yea i have really interesting weird dreams and i think it kind of means somthing, i dont know
