Cyst
A morbid collection of memories, emotions, energies, that are not harmonising or adding to your life in general.
A cyst on a certain part of the body can show a physical or psychological hurt connected with that area. So a cyst on the right leg could indicate weakness in your confidence in external activity. See: abscess boil.
Useful Questions and Hints:
What memories, emotions, energies are causing me problems at the moment? (Imagine going back into the dream and drain the cyst, or apply healing cream to it.)
Have I got a physical condition or pain in the area shown – if so might it be a good idea to have it checked?
Does my dream give me any clues to its cause?
