Towers symbolize ascending. In the Middle Ages, towers and bell towers could serve as watchtowers, but they had a meaning of a staircase between earth and heaven (in those times, material height was associated with spiritual height). On the other hand, towers also symbolize isolation from the world in which you live, so to speak, the defense from external aggressions. A solid tower signifies that you are confronting the challenges that are thrown at you in life perfectly; a half-demolished tower, in contrast, represents the opposite.Seeing a very tall tower foretells good luck. But, if you are coming down from it, it predicts failures.
