People who experiment with psychoactive drugs like LSD and magic mushrooms frequently report spiritual fantasies. Furthermore, psychiatrists have deemed many visions the result of sleep paralysis, a poorly understood condition in which the afflicted wake up and find themselves unable to move.
Scientists have yet to pinpoint the roots of this phenomenon, but some think it occurs when the brain crosses wires between conscious awareness and the dream-filled REM stage of slumber. According to a survey in the International Journal of Applied and Basic Medical Research, at least 8 percent of the general population and around 30 percent of people with psychiatric illnesses have reported having one of these nighttime episodes at some point in their lives.
Many cultures even have a specific name for the ghoulish occurrence. In the early s, British engineer Vic Tandy was working in the research lab of a medical supply company when a strange feeling came over him. All at once he felt frigid and overwhelmed with a sense of impending doom. As he paced around the room to calm down, he suddenly sensed an ethereal presence. Moments later, he was sure he saw a gray apparition in his peripheral view.
When he whirled around, the specter was gone. The culprit turned out to be a fan that hummed at a rate of Waveforms that dwell around this acoustic sweet spot and below are known as infrasound.
In fact, after Tandy published his findings in in the Journal of the Society for Psychical Research, For Tandy, the fright left him more curious than ever about ghosts. Consider the rural town of Anson, Texas, where locals long believed that if you drove out to the crossroads nearest the local cemetery and flashed your headlights, a mysterious flicker would bounce back at you. Legend held that the blink came from the lantern of an ill-fated mother searching for her son. In , a group of skeptics armed with iPhones and Google Maps confirmed a less evocative explanation: Cars coming around a bend on a nearby highway cast the eerie beams of light.
Some historians believe that rye bread contaminated with ergot fungus the same microbe from which LSD is derived may have triggered the presumed possessions that led to the Salem witch trials of the late s. So far, the evidence supporting this hypothesis is pretty thin. Your mind is playing tricks on itself In recent years, neurologists have identified potential bases for the feeling that someone or something is haunting us.
Research suggests seizures in the temporal lobe—the area of your noggin that processes visual memory and spoken language—might trigger ghost sightings. Electrical disturbances in this brain area could make us feel connected to otherworldly realms. Research suggests that the brain may summon spirits as a means of coping with trauma, especially the pain of losing a loved one. One survey in the British Medical Journal found that close to half the widows in Wales and England had seen their mates postmortem.
Experts think that such specters help us deal with painful or confusing events. A analysis published in the journal Death Studies looked at hundreds of incidents of supposed interaction with the deceased.
Studies suggest kids who are bullied or exposed to dangerous situations are more likely to have paranormal fantasies, a trend psychologists also found in adults with a history of childhood trauma.
In a survey in The Journal of the American Society for Psychical Research , 91 percent of participants said their encounter had at least one upside, such as a sense of connection to others. So if you do see a shroud down the hallway, you might not want to run.
Ghostly occurrences can be the result of larger problems in our gray matter. For some, hearing voices or experiencing a vision can be an early indicator of medical conditions such as schizophrenia. Some evidence even suggests that people with underlying brain disorders tend to have paranormal confrontations that are more intense and negative than the average brush with the beyond.
Even in those without mental illness, temporary changes in brain activity can lead to run-ins with wraiths.

Many cultures even have a specific name for the ghoulish occurrence. Sometimes people experience an otherworldly encounter simply because something in their environment is making a strange noise that sends their bodies into disarray.

Can hair truly turn white overnight from fright?
In a May paper in the journal Cortex, psychologists from Goldsmiths College in London wrote about their attempt to do just that. IE 11 is not supported.
