Spirits or ghosts haunt only because you have not let go from the past or they have not let go from the past.

If you have a artifact that some one had while dieing or if it was close to that person at the time, could be a reason why that some one or something is still lingering in your home. A example of this type of haunting is; my mother had too-ken a few objects to remember my uncle who had committed suicide that where at the scene. No the body was not there if that; what you are wondering but he had already been taken to the funereal home. Anyway, when my mother had took en the few objects home, including alcohol which my uncle loved to drink, which was most likely a big memory to his ghost. Over a week or so, everybody in the house started having weird dreams and seeing unexplainable things. Even at one point, my mother was flipping through her phone and his number dialed it’s self. This then added up to fact of my mother getting rid of the items causing the ghost to not linger in the halls of my home. So if you experience something related to this, let go of the memories before it opens you up to a demonic realm.
