I believe that children this small have a sensitivity to paranormal. If I were you, I would look into the history of your home. Check newspapers at the library for deaths around your area or even talk to neighbors who've lived in that town for years. You might stumble upon some very interesting findings.Your best bet is to announce out loud for this "boy" to go home. I know it sounds silly, but if this spirit is frightening your little boy, this could really help. Next time your son acts strangely and points to the ceiling or watches the wall, etc...., say something out loud like "your not alive anymore, go home."You should watch sylvia brown on Montel, wednesday mornings. Its just an idea. There's people who go on the show who ask her these kinds of questions all the time.I hope this helps!
