Dream: Barking Tornado

I only remember one scene of the dream.  I was in the house with Dad looking out the window.  The house was significantly white and had little or no furniture with large windows.  The view from the window was unnaturally clear; there was no more than three trees.  I was watching the sky when a tall thin white tornado started to form.  Before it fully formed, I tried to warn Dad.  He had been talking and continued on, walking around the house behind me.  As it formed and began to move our way, I asked Dad if we should take precaution but he started rambling about something else.  Just before the tornado reached the house, I dropped to the floor for safety and Dad noticed and did so too.  As it hit, the bottom of the vortex lifted from the ground and passed over the house.  I got up as I realized that it had passed but then it came back and took the roof off the house, however, it had no effect on the inside of the house.  Before the tornado hit, I was inordinately terrified but after it passed the first time, the fear passed completely.
