We dream because when we sleep, our brains go into Defrag
mode.
But when you get knocked out by Local before surgery, it's like
someone turn off the lights. You blacked out, dreamt NOTHING, and
wake a few hours later but felt like it was a minute ago.
We dream because our brains are alive. We don't dream when we get
knocked out by Local because although our brains are alive, it was
sort of like being halted in mid function.
So, when we die eventually, it's the same - LIGHTS OUT.
