Ok this happened a long time ago, but i still rember it. My mom used 2 b a party girl.We had just moved in 2 my grandmas house.So my mom was at a party(of course!)and my grandma was on a cruise.So I went 2 bed it was about 12:30 at night and my mom didnt get back until 7;00 in the morning.So all asunded a big thud came from upstairs, so of crouse i went up stairs and saw nothing. But a picture was broken and our vase too.i was so freaked out so i said "whos there?!?!?!Then i went back down stairs and 30 min. later a big thud came from up stairs and so i went back up stairs and saw a figuer then i looked away for a sec and whatever it was it was gone.I have not told anyone besides my friend and sometimes i hear a big thud from up stairs.
