the house they moved into was haunted but they didn't know

Tommy was 10 and both of his brothers, Wilbur and Techno, were 16 since they were twins and didn't want to play with Tommy, so he went exploring in the attic. Their dad, Philza, was out and the twins were meant to be looking after Tommy but they couldn't be bothered so they just let him do whatever

in the attic he found you, a doll inside a doll house. The exact thing happened to you when you were eight, you were bored, found a doll house and played outside and you got killed...no one knew about this so you were reported that you were missing and your soul possesses this porcelain doll. The house is haunted by multiple ghosts, like yourself, some good but most are bad. So you try to warn him as he plays
