Old factories or mills are often considered "haunted" because of their history of potentially tragic accidents, harsh working conditions, and the large number of people who may have died on site during their operation. These factors have led to stories of lingering spirits attached to the building due to the traumatic experiences associated with the location. The dilapidated state of many abandoned locations also contributes to a spooky atmosphere, further fueling the belief in hauntings. Furthermore, old mills are also located near moving bodies of moving water (waterfalls), which could potentially act as fuel for the spirits to manifest.

Because museums house historical artifacts and objects that may hold strong emotional energy from their previous owners (including their remains), it is commonly believed that spirits can become attached to these items and thus the locations where they are kept and placed on display. This is especially true if the items are associated with tragic or significant events, making the museums potential hotspots for hauntings. These hauntings can manifest in various ways, such as unexplained sounds, sudden temperature drops, or even sightings of apparitions. Consequently, many museums have adopted ghost tours and paranormal investigations to explore these intriguing phenomena, attracting visitors curious about the supernatural.

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.
