#5 – Exploding Head Syndrome
You may have fun in a heavy metal rock concert, but what if you hear extremely loud noises right inside your head? You will probably not enjoy that. Patients with exploding head syndrome have auditory hallucinations and hear loud noises in their head. These sounds can be in the form of bombs exploding, guns being fired, or cymbals crashing together.
The sound is quite loud but not painful. These sounds are usually experienced at the onset of sleep or within the first one to two hours of falling asleep. Sounds may be accompanied by bright flashes and the person may experience fear and anxiety just before the attack happens.
