Tornado

Last night I dreamt that I was in a house when I heard a very loud rumbling noise outside.  I opened the door to see a wall of dirt and debris and wind moving slowly past.  Suddenly, I realized it was a giant tornado and that my children were alone in our house on the other side of the field.  I ran outside and around the tornado in an attempt to get to them, to make sure they were safe ... but my house wasn't there.
