I don't really believe in ghosts but there has been unexplainable things going on in my home. I've lived here for 14yrs.We recently remodled and added 3 more rooms and a bath. Before it was just 2 rooms and 1 bath. I have 4 children.(14,12,10,6) I gave my old room to my oldest daughter. Which she will not sleep there by herself. She says she keeps hearing noises.I remember times when I myself would hear unexplainable noises and wake my husband up in that same room. My son who got a newly built room says he hears knocking or thumping on his walls. They all sleep in one room because they r scared to sleep in there own. I'm a stay at home mom and here strange noises or thumping through out my day. I've always said it could be a mouse or something in the walls or roof. But I have also heard something fall in another room and will go check and there is nothing. Just yesterdays I had a friend over and she said she heard like a ball bouncing against the bathroom wall. I guess I just always came up wit some sort of reasoning for such things, but know I'm in dout. These things are happening more often. Could it be spirits? How can I get rid of them or it?
