So anyone who knows anything about ghosts.. You don't have to believe in them nesicarially just have more knowledge than an idiot

So my friend apparently has a ghost that follows her/her family and one time her sister had a dream where the ghost was telling her to kill my friend and that my friend owes her something...
Is there a way we can ask the ghost what it wants/ why it wants my friend dead?
We need the experts here I am willing to share all I know about ghost child and what they have seen in all of their houses
There are more stories about her and all of her family, even her grandma had seen her
I'm not sure if I fully believe her but her stories are way to consistent to be fake and her sister had a tik tok about her dead mirror flashing

We also don't have access to a ouiji board or I would have already suggested that to my friend
