Very true, there's a reason I picked up on the topic, and it's because i've experienced what I call black outs, now when it happens, I can do nothing in way of responding, but i can hear everything, even though I can't respond. I assume that happens, because the body needs to shut everything down, so the blood can still get to the brain. Basically someone would feel my pulse, and im laying there thinking in my head, I ain't fooking dead yet yer know, oi shut that coffin back up....and then I come round. So it got me thinking, maybe there is some truth in it, albeit the blood is no longer going to your head.
