Ghosts vs discarnates?

my oldest daughter has that gift along with seeing as well as far as communicating with them she cant...she never has seen as much point to it but usually when a person close to the family dies they always come to her but she never knows what for, this used to scare the crap out of her when she was around 3 or4 when she first started feeling a presence...my mother helped her through this till she ped on my mother promised her she would never be visited by her and its been 5 months sinse my mother ped and she hasent seen her..if you know of pple that might be ping on the best advise i can give you is to ask them not to visit you after thy are gone it helps my daughter
