Ah, had another thought.

About the homeowner (instead of God - the subconscious is not really that philosophical) Ask yourself if you are feeling you are living life on a borrow? Do you feel that your life is not really your life, that you are not the owner of your life? Now we have not just your relatives bossing around your life, but you are not even the owner of your own life, your own stuff! Is that how you feel? Is asking the question if that is how you feel reveal something to you?

If this is what it is, then this whole thing is about insecurity and fear. The homeowners relatives take on a sinister bend from the get go, even before they turned into ghosts.

How do you feel in the dream when you are exorcising the ghosts?
