Sam, I have had friendly entities as well as violent entities in the house. If you feel uncomfortable, be assertive and tell the entity to leave. I myself have experienced paranormal activities in stores, other people's houses, outdoors, and other parts of the country. I guess I'm a "ghost magnet." My last physical encounter: I was visiting my parents grave site; after talking out loud, It felt like fingers tapping on top of my head (harmless). I too have experienced children laughing and running in the house. I've seen handprints and footprints in the house.
