If your spirit is persistently harmless or if it has shown itself to you, in a non-threatening way, then you most definitely have a ghost. The ghost can be frightening, by its very nature. But the ghost will never intentionally frighten you. They will be there for three reasons: 1. They used to live there and are attached to the location 2. They are trying to communicate something to the living or 3. They are protective of somebody who lives in the house and so they are “standing guard” so to speak, over the loved one.
