I enjoyed it. It was hard to decipher its meaning. I thought perhaps it was about the frustration of the individual in the modern world; at the mercy of events and powers greater than himself (like nature). The illusion of normalcy is the dream we escape to to deal with the crushing sense of inferiority. Tornados in dreams signify feelings of losing control.
