It is possible. There's so many people here in the world that are demons. Oh and it's easy to make a deal with them, if you have the money.

The thing about bargaining with the devil himself is that he's not gonna wait around for you to live your life before he takes your soul. With a regular demon, you don't have to pledge your soul, just some blood. With more powerful demons, you have to be careful because they will try to kill you. If the demon you summon is more powerful than you, it will be able to kill you, so you have to find some way to gauge your own strength before a summoning.

However, it sounds like you might be haunted by a demon and want to get him out of your house? That's a different matter altogether. See, once a demon has entered our world, it doesn't want to go back. What it wants is to attain physical form, which it can do as it becomes more and more powerful. The demon creates fear in humans and feeds off that negative emotion. As it feeds, it gets more powerful and has more ways to scare you. If you have a demon that is interacting with physical objects(like throwing things around a room) you have a big problem. Once it is powerful enough, it will possess someone and use them as a tool to attain even more power. When they are in possession of someone, they can kill other people and absorb their souls, powering them up much more than when they feed on fear. Very few times in human history has it ever gone this far, and I don't know that there are any times when the demon has actually been able to create its own body. Such an act requires and enormous amount of energy and if it were ever to happen there would be a lot of trouble for us humans. You see, most gates to Hell do not allow physical beings to pass through, but there is one gate somewhere in the world that is currently closed that could do that. If a demon attained its own form and opened that door, the apocalypse would be upon us.

As for getting rid of a demon, you would need a powerful exorcist, one capable of overwhelming the demon and forcing him back through a gate into hell. Once banished back to Hell, a demon could not come back for some time. You will also want the exorcist to check and see if there is a gate in your house and close it if there is. Only one demon can occupy a house at a time, but if one is forced out another can make his way through the gate. Now, the further along your demonic haunting is along, the more powerful an exorcist you will need. Remember this: crosses and holy water only get you so far. They can hurt demons, but a demon is trained to handle pain like that. The real factor is the strength of an exorcist's soul and the strength of the demon in question. You could bring in multiple exorcists to defeat a more powerful demon, but you have to make sure the combined strength of their souls is greater than that of the demon. If you want to kill the demon, forget about it. The only way to do so is on their own turf, in Hell, or with weapons that utilize the power of Holy Light, which cannot be found on Earth. Your best bet is to force the demon back through the gate and then close it.

seem to know alot...

Yeah, I actually made all that up and don't believe a word of it, but if you are going to believe in demons, what I just said is more information than you'll find in most places.

Making a deal with a demon is like the story of the hunter and the bear, the bear says I want something in my stomach the hunter wants a fur coat, the bear is the only one that comes back and they both got what they wanted. o.o
