Jinn
Dreams are often known to be attacked or fight a Jinn inside their house in dreams. Usually these spirits or demons represent unconscious negative forces that seem to possess the dreamer. This is not an actual possession but rather a metaphoric one relating to bad behaviors, negative traits, addictions and negative emotions. Once it is in your house it becomes a part of the mind or psyche of the dreamer. Once you are fighting the jinn it becomes a positive symbol that you have now made this unknown force conscious to you.
