If you are absolutely sure that there is ghostly presence in your house and you want to do something about it then there is very little information out there which is actually true and you could do a lot of irrelevant thing, since this is not something that happens very commonly there is only a handful of experts and with their experience only they can tell what works best in a haunted house, not everyone can talk to a friend or a family member about it because that sometimes makes it worse, rather than helping they get spooked and stop visiting your home which is the last thing that you would want at that time and similarly not everyone has the access to a professional paranormal expert and they might charge you as well.
You have no one but yourself in this situation but thanks to technology you can put things right, the first step is to make sure that there is a ghostly presence and there are a few ways through which you can check, secondly what you must do is record the sightings or the noises, no one would believe that something just flashes by the corner of your eye multiple times a day and they might not even believe that you are having cold spots in your home or untraceable smells which can’t be explained, but if you get something on camera you can then get help.
Thirdly you have to stay calm and I know it is easier said than done but you have no other choice here, haunted house in Ohio was the only other place I got scared but these ghostly presence at my friend’ place have really freaked me out but thankfully we managed to get things on camera and go the help from the experts.
