First off let me say I am so sorry you are having problems. You have been offered good advice here already so I don’t have much to add. Your intentions will play a huge role in your success in ridding yourself of this. Set strong intentions and be positive. As far as your soul , it belongs to the creator (in my opinion), and I don’t believe something can harm it. If you do have a negative entity bothering you, fear is what they feed off of, so scaring you in your dreams is a good opportunity for them. Go over those forum suggestions and try to lighten up the vibes around you. Be positive by cleaning house and removing clutter. Stale energy is not good. Open your windows and change your furniture around. Play uplifting music. Doing small things can totally lift your spirits and that is super charging your spiritual immune system.
