According to a study conducted by the Washington State University there is significant number of people experiencing this but previously it was thought that it happens mostly in older adults.
Exploding head syndrome is where the person is awoken by a loud noise but this didn’t happen in reality and it is all in the mind.
American Sleep Association Describes this as, “Exploding head syndrome is a rare and relatively undocumented parasomnia event in which the subject experiences a loud bang in their head similar to a bomb exploding, a gun going off, a clash of cymbals or any other form of loud, indecipherable noise that seems to originate from inside the head. Contrary to the name, exploding head syndrome has no elements of pain, swelling or any other physical trait associated with it. They may be perceived as having bright flashes of light accompanying them, or result in shortness of breath, though this is likely caused by the increased heart rate of the subject after experiencing it. It most often occurs just before deep sleep, and sometimes upon coming out of deep sleep.”
They also added this is due to stress syndrome.
Brian Sharpless, director of the university’s psychology department, interviewed 200 students and it was surprising to found that one in five experience exploding heads.
He said, “Some people have worked these scary experiences into conspiracy theories and mistakenly believe the episodes are caused by some sort of directed-energy weapon.”
In many cases it was associated with sleep paralysis where the person wakes up in the middle of the sleep and cannot move.
There is no treatment at present to cure this syndrome but Sharpless said there is one drug which can turn the volume down.
According to ASA reducing stress could help it.
