Spirits are a one on one experience, it depends on an individual whether he or she believes in them or not. Nobody really knows whether they exist or not, some people believe in them and their existence. There are many paranormal societies which research and believe in the existence of ghosts and spirits and have even captured them on photos & videos.
Spirits cannot be necessarily called ghosts; one can experience negative energy around them which they might confuse with a ghost too. There are many dimensions in which energies live in and as common people we do not know about what exists or not. Some people do have the tendency to sense spirits and ghosts more than others simply because of their sixth sense or enlightened sensing powers. Paranormal societies research about negative energies rather than ghosts and prove their existence by scientific ways. There are ways they try to connect and communicate with these souls or energies.

A spirit or a ghost has the air element more in them and is in gaseous state which is tough to see by us humans. That is why we can only feel spirits and not see them.
Where do they live?
Negativity attracts negativity; a ghost will always be felt in negative isolated places. Ghosts or spirits do not live in the same dimensions as we live in that is why they try to communcate with us which generally scare us but is the only way of communicating with us humans. All spirits are not negative, some of them are just trying to communicate while some of them are trying to harm us or use our bodies to come back to the world.
