The dream, in which the one dreams of not having a soul, indicates the state on the dreamer which is helpless. The one is unable to recognize himself as more than a body. The dream could also show that the dreamer is feeling ashamed of himself, therefore he feels soulless.

Alternatively, the dream may symbolize the high spiritual state of your mind, especially if the dreamer sees his own soul.
