Hey people, I was doing some research online and came across this thing called Exploding Head Syndrome... It says: "Exploding head syndrome is a condition...that causes the sufferer to occasionally experience a tremendously loud noise as if from within his or her own head, usually described as an explosion, roar or a ringing noise. This usually occurs within an hour or two of falling asleep, but is not the result of a dream...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 (when perceived on their own, known as a 'visual sleep start') or 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" Something sound familiar here?
