Generally, they don't want to hurt you, nor would they. Ghosts are very different from poltergeists, and demons and what not. Ghosts are usually an energy that is still hanging in there, sometimes they are aware of you, others aren't. Those would be residual hauntings, and they just go on about what they used to do when they were alive never noticing you.
But a ghost that is aware, can do minimal physical things by drawing in energy from the surroundings. Like move something, or hide something from you. Sometimes, they leave a perfumy scent in the air, or cause a small draft, and sometimes you might be touched.
If you feel threatened by it, then I would look to have a priest bless the house for you. If you aren't threatened by it, by all means, enjoy the visits that they do, sometimes they are very pleasant. If you don't want them to come to you, and they are aware of you, you can ask that they don't visit you when you are at home, usually they will listen to you. Hope this helps. God bless.
