The twitch right as you are falling asleep is known as a hypnic jerk. The flash of light may be related to exploding head syndrome. The faint "music" could be tinnitus, some electric device (speakers, guitar amp, etc.) picking up an AM or shortwave radio station, or just your brain making up (or playing back) music as you drift off to sleep.

THANK YOU

Hypnic jerk is my thing, and im male - and have all the halmarks such as chronic insomnia, but just started melatonin.

But wow - yeah it scares the heck out of me, yet the wiki says "benign" so that is thankful...

A morbid dark, intrusive thought that has happened to me when these occur is that my heart stopped due to sleep apnia and that I was startling myself back alive...

however these occur even when I am not yet asleep and in twilight mode.

SIDS ;;

This reminds me of what the believe the cause of SIDS to be: a pocket of co2 around the infants breathing-bubble where they are just recirculating the CO2.

So, I wonder if the infants dont yet have the ability to startle themselves back awake... but adults do.

I have had two people close to me who have had SDIS babies, and its horrifying.

A small crib fan may prevent CO2 bubbles...
