Death again. Hello sir. Simply put, this is a 4 minute version of the (usually) flippant statement "I wish I was dead." 
Not many people genuinely do wish for that, but I know how it feels to wonder about the relief that the nothingness would bring. 
I imagine no noise, no light. Fucking nothing. Maybe a drip feed of single malt whisky though, if I'm lucky enough to get punted down to Hell.
