Are you scared of ghosts? They're the soul or spirit of a dead person or animal
Yeah I am scared of ghosts, mostly because I don't understand it I think
It is believed that they haunt locations, objects, or people that they were associated with in life
That is what I have already heard I just wonder why they do that?
I'm not sure, but many probably try to find out when they attempt to contact spirits in a séance
Now I am really scared of seances
Ghost probably wouldn't harm you. They are generally described as being solitary, human-like essences 
I always thought ghosts seem sad like they have regrets or something
That's possible. Many practices of spiritualism and ritual magic are designed to put to rest the spirits of the dead.
