really weird dreams

okay i had these two dreams, both of which have to do with tornados. the first one i had involved me going to my sisters friends house and hanging out with her friends. the next thing i know i look outside and a tornado has formed and i yell at everyone to get into the basement, but right as i hide the whole house gets torn aprt and my sister and i are left standing. then the tornado comes back at the house, so i hide in a van. as the van gets lifted up i notice a sunroof open and as i reached my hand to close it i litteraly felt my hand eing succtioned while i was dreaming . it was crazy, and the dream ended when the van hit a house. the other dream has to do with me being in my grandmothers house and the tornadoes keep forming in the valley and in a reppetition, keep coming towards the house and as i hid in the garage it got blown away and i could feel myself actually spinning, just like i felt the pressure from the first dream. in the dream i called my mom and she said there were no tornadoes there then we lost connection. after that our family went outside when we thought it was clear and one came at us andit made the umbrella in my hand fly out, yet the tornado never touched me. if anyone knows about a dream book i can look at, or can decode what my dreams mean please let me know.

well i'm wondering what the heck is making me dreams these.
