Allo.

I was wondering, is there a specific name for the state of conciousness when you're extremely sleep deprived and are at a point where youre trying to keep your eyes open but it's extremely hard and you're sort of on the brink of sleeping as your mind can't always depict reality and have mini time lapses?

Also if there is a specific name does making yourself this tired increase/decrease the change of having a lucid dream or even a dream at all?
