I don't really know what you should do. But I know that whatever you do, you must believe your son. Children are very open to seeing spirits. Just so you know that you are not alone, my child also see's spirits. He is now 4 yrs old. He probably saw them when he was an infant but it wasn't until he could talk that he made me aware of what he was seeing. When my oldest son was about 4 or 5 years, I had taken a picture of him and after getting the picture developed I had noticed a bright light that was in the shape of a child standing behind him. My 2 year son points at things and laughs alot. So all my children do see spirits. I am fortunate that they have all been friendly. I wish I could be of more help to you, but I just wanted to let you know that you are not alone with this issue.
