Lights off is very real and very physiological when it comes to attention paid via hearing. Human hearing is an alarm system which never sleeps. But it does vary in the brain power allocated to it.
At night it can save your life, so when dark, it becomes highly attuned. Highly. Shut off the conscious mind and the eyes, then the hearing really perks up. Maximum attention, maximum brain power applied, when it comes to sustained darkness. It is an autonomous function or process, for the most part. Outside of your conscious control, to a notable degree. Just like all parts of our day to day cyclic but varied (in level) functions.
It’s built right into you. Core function.
