Strange dreams?

Are these just dreams?I live in Tampa area. About 7 years ago i had a strange dream. I was in my parents back yard and looked towards the southeast and saw a mushroom cloud. I knew in my dream it was Miami. Was scary dream and even though miami is about 7 hours drive , there was rocks falling on my head. Move forward. About 5-6 months before Tsunami's i had dreams of giant wave coming towards gulf coast of florida. Never thought about dream until Tsumani happend. Move forward. About 6 weeks before Katrina had another dream of a big wave but seemed to be caused by storm. Now i remembered 1st dream about three weeks ago when i had another one where i was high above a stadium looking down at it. 3 objects went down into the stadium and saw a big blast. In my dream i knew that the stadium was in Miami. The next thing is i was standing on ledge of a building and that building and all of the other buildings started falling but not like the WTC but like cig ashes. Is this just a dream
