Houses might be considered "haunted" if the people living in them died in a tragic way or experienced a traumatic event in the house, which would leave behind a "residual energy" in the space. Conversely, a person who lived in a house for a long time and had a strong positive emotional connection to it may leave behind a lingering presence even after they have died as well. Historic homes are more likely to be haunted because they have seen more significant events. If the house is younger, it is also possible that it was built over a burial site that was previously used, and the concentration of the area was shattered when the graves were disturbed. This scenario could potentially lead to paranormal activity because the property is being disturbed rather than the structure itself.

Most people believe cemeteries are void of paranormal activity because they are consecrated or because spirits don't return to their graves. However, cemeteries are often considered "haunted" because of their association with death and the unknown, as well as stories of disturbed graves, unmarked burials, tragic deaths, natural disasters that disrupt resting places, and the general sense of sadness and grief that surrounds a graveyard. All of these factors lead people to believe that spirits might linger in cemeteries.

Hospitals or nursing homes are often thought to be haunted because they are places where people frequently experience extreme pain, suffering, and death. These experiences can be believed to leave behind lingering spirits or energies that may manifest as paranormal activity. Essentially, the high concentration of significant life events, particularly tragic ones, could create an environment where some people believe ghosts are more likely to appear. Some believe that hospitals or nursing homes would be a type of location, much like battlefields, where thousands of lives were lost in a small concentrated area, creating portals for souls to be transported to the other realm.
