is this weird

Hi ilianag16, It is weird, to say the least, that you think your sister is seeing ghosts or being haunted by them. If you all lived in the same house before you and your mom moved, did you ever experience any kind of paranormal behavior around in the house? Why would the ghost wait until you two leave the house to start hanging around your sister. What does your dad and mom say about this siutuation? Do they plan to do anyhing like bringing in a ghost hunter? You said you think, how about your other family members. Do you have any evidence that the ghost are following your sister to you house. What if the ghost is at your house and only comes out when your sister comes to visit. I hope you figure out where this force is coming from, your house or your dad's Good Luck
