Thread: Why aren't we always lucid

I think the reason why we are not lucid every night is simpler than everything that has been written in this thread so far.
We are not lucid because we are not supposed to.

It has been proved that during non luci dreams, few parts and functions of the brain (and a certain kind of neurons) are turned off.
This must have a biological reason. (hobson gave some)
I see lucid dreaming as a way to hack the brain.
When those parts and function are turned on (because of prospective conditioning : DILD techniques, or because it has not been turned off :WILD), the brain starts to work more like it works when awake.

The parts and functions involved in the sens of self, and few other functions, probably need to rest while other parts need to keep working during a certain fraction of the night.
Plus maybe dreams are supposed to be rather random and with free idea associations, a cat becomes a tiger few seconds later, a yellow umbrella becomes a yellow stick and so on.
Because dream events are succeeding this way, in an illogical and inconstant way, if the functions involved in the recognition of illogical or weird events were not turned off, this way of producing dreams would be compromised and it's purpose (whatever it is) too.

Lucid dreaming is a way to make the brain work in an unnatural way, that's why I see it as a hack, or a glitch for occasional and spontaneous LDs.
