This happened a few moths ago at my mates house in Sydney. He has a few ghosts in his house and not only have I but my other friends have seen them. One is a little boy and a little girl (who walk around the dining and lounge room), another is a Woman (who looks after the main bedroom) and another is a big dark man (who stands in the door way between the kitchen and the dining room).
On this occasion there were three of our mates in Taylors bedroom (a boy by the way) me and my other mate were sitting on the bed joking around and Taylor was at the T.V getting the DVD we wanted to watch together. This is after all the chatting and being total idiots in the lounge room. So by this time we all know there are spirits in the house, evil ones and down right scary ones with nuetral intentions.
I called out to Taylor to put on the DVD but he told us that it was out in the lounge room and none of us wanted to go out there because of the experiences we had all night. Me jokingly said "yea Taylor go out and play with all your friends", as soon as I finished, the deepest most demonic voice, clear as day comes out and says "Yeah You". As soon as this happened me and my mate on the bed looked at each other in total shock. Mouths wide open and looking straight into each others faces, Taylor turned around laughing thinking we were joking around, until he saw our faces so he jumped on the bed and we all sat there freaking out.
After about 20-30 minutes we heared scratching at the door, and I thought it was the dog, the others not wanting to go near the door I got up and opened the door only to be greeted by nothing. I closed the door and sat back down and my mates asked me what happened and I told them that nothing was there, straight after Taylor could feel the bed lifting up under him, and I saw it happening.
His house is so scary, as this isn't the only time that something has happened. Another night that I stayed there, there were a few of us this time like 4 if memory serves me right. But his parents were asleep and snoring and he is an only child, so it was just us and a few other friends at 2am in the morning. We were talking about ghosts and I could hear something, I quickly hushed everyone and they could hear it too. There was a full conversation going on in his grandmother room (she has passed away a few years ago) with a man and a woman, and it was a normal casual conversation with whispered laughing and responses within their conversation. No one could understand what the words where but we all stood still for a good 10 minutes listening to this whispering in the grandmothers room.
The door scratches again at the mothers room, and again I thought it was the dog wanting to come out with us, and it was but this time myself and Taylor got up to open the door when it opened without us touching it, so we stuck our heads in to see his parents sleeping and snoring, when we go to close the door a hand comes to the door knob on our side and the door closed. The hand was scratched and dark, I believe it was the woman who resides in the parents room.
Another thing but by far not the last thing that's happened, I was talking to a little spirit boy who had been burned, just with my gift that I have and how I communicate with them. Anyways I got the feeling that the boy was burned and he answered with a yeas and after the conversation me and my mate went to go get a drink and there was a little finger print in soot on his white table, with the chair slightly out as if someone had leaned on it and the smallest handprint on his chair. We all tried to mimic the hand print on other chairs and even tried different positions to decipher if it was in fact one of us or a spirit, and it was a spirit. The soot was also in an obvious place to be seen and his mother cleans this house like there's no tomorrow so its always gleaming, so the finger print stood out even more.
So yeah these are only a hand full of experiences from my mates house:)
