WEIRD THINGS, like ghost,ufo.........ever happend to you

i think i have seen not ghost but something like that i am talking about 1993-1994 we lived in the house i and my family realized something strange about that house, when my father and mother went out side or sometimes when everybody got sleep i heard someone was talking in the kitchen and sound of spoons like many spoons were pushing and striking i heard same sounds like that many times but when i went into the kitchen no one was there and no sound at all. and one day i saw my father he was coming up stairs he smiled but suddenly when i saw the stairs again no one was there even my father was not at home at that time so i saw something i dont know what really it was.
