It is a widespread problem: household doors opening and closing without your assistance. Closing doors are especially problematic, as they can keep your home from heating or cooling evenly, trap pets, or cause a midnight ruckus when you walk into one on your way to the bathroom in the darkness.
It could be that your property is built on an old cemetery, there were brutal murders in your home in the past, some or all of your house is possessed, or some spirit is having a hard time crossing over and wants to pester you with its free time. Or, your house could be settling and the change is unnoticeable to everyone except your doors. If it is a supernatural thing, consult a medium or exorcist. Otherwise, there is a simple way to keep your doors in place until you are ready to close them.
The hinges on your door are made to keep it hanging on the door frame and open and close with as little effort possible. This works great until something happens that shifts the doors slightly off kilter, then they just follow the force of gravity. The easiest solution to keep doors in place is to add more friction in the hinges. Here is how you do it.
Using a skinny punch or screwdriver, place the tip on the bottom of the hinge pin. Tap as hard as needed to free the pin. Remove the pin. (pro tip: start with the middle hinge first. The top and bottom hinges will keep the door even and make removing and replacing the pin much easier).
The key to adding more friction in your door hinges is to make the hinge rotation around the pin a little more difficult. Place the one end of the hinge pin on a small block of wood and the other on a hard (preferably the garage floor or driveway) surface. Strike the middle of the pin lightly with a hammer. Repeat as often as necessary to produce a slight bend in the hinge pin. It should be slight enough that it is barely noticeable
Installing the hinge pin is the reverse of taking it out. It may take a little more effort to pound it back into the hinge since it is now bent.
Depending on how much gravity is pulling your door open or closed, you may need to repeat the process for one or all of the other hinges. If the door still has a mind of its own. Repeat on each hinge, adding a bit more of a bend in the hinge pin.
And that is how you correct one of the most common and annoying problems in your home. Simple and effective. However, if after repeating the process on all of the hinges several times and the door still opens and/or closes by itself, it is definitely a ghost.

So useful! Taking a break from the final finishing of an addition we just finished refinishing doors in an old section of our home. Reinstalled, one of those doors opens slowly all by itself if it is not shut into the frame. It creeps me out if I'm not paying attention. Thankfully, my partner in crime knows the info you've provided. If not for him I would have to follow these instructions.
