There has been some research with anaesthesia that indicates that when the brain is shut down by the various drugs, when it wakes up again, it boots up something like a computer, with various functions coming 'online' one after the other. This is a bit more complicated than the booting of a computer as a computer can be completely turned off, whereas completely turning off a biological entity is death. Some operating systems have a sleep mode, so the computer is still on, and the system comes back on-line with the touch of a key or other input device.
I can tell you that a deep anaesthesia state is extraordinarily blank and that the boot up from that is a much cleaner experience than awakening from sleep which is rather erratic by comparison, as with properly administered anaesthesia you are coming out of nowhere, and sleep has more levels of brain functioning active. ---In FairfieldLife@yahoogroups.com, <seerdope@...> wrote : "As you always hear your alarm clock when it goes off in the morning you must have *some* awareness even in the deepest sleep." Is my PC actually on, before it is turned it on? (And of course my alarm goes off in early morning hours when I am already habituated to begin wake up -- in a day dreamy state or in REMS or Non-REMS 1 or 2 stages. I have at times missed the alarm when in very deep sleep). "Because to doubt its reality is itself an act of awareness. " My awareness (has) doubt(s) the reality of my awareness in vast numbers of multi-universes. Does that prove the existence of multi-universes?
