does anyone else get this?
i kind of assumed everyone did - but apparently it is quite rare

"Exploding head syndrome (EHS) is a form of hypnagogic auditory hallucination and 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, ringing, an earthquake, or any other form of loud, indecipherable noise that seems to originate from inside the head.
This noise usually happens at the onset of sleep or within an hour or two of falling asleep"

more here - http://en.wikipedia.org/wiki/Exploding_head_syndrome

mine seems a bit different to what is described there - the noises tend to be kindof synthy, like a really rich, punchy, buzzy synth note, with high and low tones, lasts about 1 or 2 seconds, and i'm always totally aware that it's coming from inside my head, sounds absolutely massive. I don't get any anxious feelings or anything with them, i quite like them actually - the sounds are usually amazing.
occasionally accompanied by seeing something flash before my eyes, which i sometimes think is a cat falling really fast.

i probably get it about once every three months or so, but i had two the other night which was pretty exciting.

anyone else?
