80s/90s movie I don't really remember well but I think some kid was trapped in a house with ghosts (but they were not really the hostile type) and the main ghost was a pretty little girl. I think she had died in a fire?
There was also some old lady who turned out to be the girl's jealous sister or something like that and she might have been the killer, not sure?
I'm sorry but seriously I can't remember anything else.
Please help!
