sleep wiki:
eep is the regular state of natural rest observed in all mammals, birds and fish. Sleep is not actually "unconsciousness," but rather, it is a natural state of rest characterized by a reduction in voluntary body movement and decreased awareness of the surroundings. Therefore, since consciousness is literally the awareness of the surroundings, being asleep is just an altered state of consciousness, as opposed to being unconscious. It is heavily influenced by circadian rhythms, and by hormonal and environmental factors as well. Sleep appears to perform a restorative function for the brain and body, as evidenced by the myriad symptoms that result when an individual is deprived of sleep.

moon,night wiki:
ight has several meanings:Moonlight is the light that is perceived as coming from the moon. Moonlight is in fact sunlight reflected from the Moon. The intensity of moonlight varies greatly depending on the current lunar phase; but even the full moon provides only a faint illumination of about 0.2 lx (so full moon is about 500,000 times fainter than the sun). One cannot read books or discern colors under moonlight.
