Okay, so me and my little sister both get the creeps in our parent's house and we've lived here for more than 14 years. Now, our fears aren't entirely unfounded in our minds for a few good reasons:
1) My sis has seen shadows in the kitchen when no one was home
2) My other sister's pink barbie jeep has been known to drive itself down the hallway
3) When we pass by my other sister's room it feels like something's watching us
4) Locked doors have opened on their own.
5) When we go in our parent's room we feel like we are being told to get out immediately
6) My sister complains that when we sleep with the door open she sees a shadow standing in the door way
7) I hear things moving in the attic when no one else is home
cool I've seen a shadow in her doorway when we sleep with the door open
9) Occasionally we'll hear footsteps in the hallway when we are the only ones home
10) The dog with start barking for no reason
11) When the dog starts barking she generally goes in the kitchen and sits in this one particular spot like she's expecting someone to give her a treat.

any suggestions, opinions, or anything else are entirely welcome.

generally spirits are not violent or malevolent. no need to fear, that which has no evil intentions.
