"Who are you gonna call?...."
While I was out and away from home I got an idea on how to deal with the ghost that showed up at my house and trashed my coffee. I went home and set up a laptop computer on the table, that coffee was spilled on, and waited. About 10 minutes later the keys began to move, one word: "hello". So I typed: What do you want? Very slowly the keys moved, again, in response: "I want you to teach me how to use a computer" I could not believe this, so I said: show yourself now and he did. I asked him why a ghost would want to learn this stuff and he told that, in order to move on, he needed to learn how to use a computer so that he could complete some task of which he would not tell me about. I thought to myself: What the hell, why not? So I began to teach him basic stuff, and after several hours he stood up, said thank you, and then vanished. I'm wondering if this kind of thing has happened before. Maybe a quick search online will prove fruitful.
