Dismemberment of the body, or indeed any dream where some type of fragmentation takes place, is largely to do with being rendered powerless. It is the death, or rather dissolution, of the Self before reintegration and rebirth take place. Psychologically we need to take our old feelings and ideas apart to make sense of what is going on. This process has to take place before we can rebuild our lives. A situation may be tearing us apart and drastic action may be necessary before we can recover our equilibrium.
