Recurring tornado dreams?

For the past few nights I have had recurring dreams involving tornadoes. My first dream was a water spout. I have always been told to go to my closet in my room if there was a tornado, in my dream I am yelling at my family to come get into the closet and they are taking their time telling me, "don't worry we'll be there in a second." The water spout pes calmly through, like being underwater but moments later a dark tornado comes ripping through the house and I wake up. Again last night I had a similar dream only the tornado was coming my way as I was trying to close my closet door, and I woke up. When I dream about tornadoes they are the only dreams I die in as well. I can get shot, stabbed, whatever in any other dream but never die. What do these dreams mean?
