ghosts contact humans because they want to see what a living soul does. some angry spirits come to humans to abuse them just because they are dead and you are not. restless spirits come to humans for partial help or direction to why it died, how to get to heaven, etc. most spirits are different from themselves, yet most claim to be angry and restless spirits both at the same time. this means that they either call to you so that they can physically harm you, or they physically harm you to get attention so that you can help them. either way, these are all why ghosts contact humans.
