One factor often reported within the paranormal sphere, is the common loud bang. Frequently, individuals describe being awoken by noises, which in the current world of the paranormal; where interest and belief is sky high, deem these noises to be paranormal in origin.
Many medically related conditions exist, where people do not take in to account that they may suffer from a form of them. Charles Bonnet syndrome, Sleep disorders and Exploding head syndrome are just some conditions which not only the witness, but especially the modern day paranormal investigator do not consider as being responsible for the cause of alleged paranormal phenomena.
Recently a news report led me to look more into the subject of exploding head syndrome and its disregard by paranormal researchers as a potential cause for paranormal reports.
Those experiencing the loud noises, sometimes wake up in the middle of the night, heart pounding, freaked out by the sound of their name being shouted loud and clear. Other times she’ll be awakened by the sound of a huge crash, as if someone has broken a window or knocked over a set of dishes.

Exploding head syndrome is a condition that causes the sufferer occasionally to experience a tremendously loud noise as originating from within his or her own head, usually described as the sound of an explosion, roar, waves crashing against rocks, loud voices or screams, a ringing noise, or the sound of electrical arcing (buzzing).
This noise usually occurs within an hour or two of falling asleep, but is not necessarily the result of a dream and can happen while awake as well. While the sound is perceived as extremely loud, it is usually not accompanied by pain. Attacks appear to change in number over time, with several attacks occurring in a space of days or weeks followed by months of remission. Sufferers often feel a sense of fear and anxiety after an attack, accompanied by elevated heart rate. Attacks are also often accompanied by perceived flashes of light and difficulty in breathing. The condition is also known as “auditory sleep starts”. It is not thought to be dangerous, although it is sometimes distressing to experience. Sufferers may experience an inability to vocalize any sound, or mild forms of sleep paralysis during an attack.
Reference to the condition was made in an episode of the ITV drama Doc Martin, which was instrumental in many sufferers becoming aware that the problem was in fact a known medical condition, and not one to be concerned about.
The cause of the exploding head syndrome (EHS) is not known, though some physicians have reported a correlation with stress or extreme fatigue. The condition may develop at any time during life and women suffer from it slightly more often than men. Attacks can be one-time events, or can recur.
The mechanism is also not known, though possibilities have been suggested; one is that it may be the result of a sudden movement of a middle ear component or of the eustachian tube, another is that it may be the result of a form of minor seizure in the temporal lobe where the nerve cells for hearing are located.

Electroencephalograms recorded during actual attacks show unusual activity only in some sufferers, and have ruled out epileptic seizures as a cause. But an attack must happen during an episode. If results are normal during the test, only then can epilepsy be completely ruled out.
These loud noises are a common feature of Out of Body Experiences. In surveys, as many as 85% of respondents indicate perception of them during the onset of such experiences.
This syndrome can also cause the sufferer to feel an extreme rush of adrenaline kick going through his or her head, sometimes multiple times. In most cases, it occurs when they are in a state between asleep and awake. Some sufferers report familiarization with the subsequent fear or panic element such that they no longer consciously experience it.
In some cases repeated attacks lead to the sufferer gaining a fear of sleeping or resting, as this is the most common time for attacks to take place, and this can lead to the development of sleeping disorders such as insomnia.
With all this information taken into account, how many cases of reputed paranormal phenomena reported by individuals can be accredited to a medical condition.
Another consideration must be given attention. The high number of self proclaimed experts in the paranormal subject again does not contemplate the necessity of researching medical conditions in relation to the subject. Hence not offering a true representation of the ethos of their authoritative opinion, this also begs that mediums, psychics and spiritualists offer incorrect views as to their explanation to those coming to them with issues spiritual in nature. Again offering incorrect evidence and false opinion to the witness.
