Why do lights flicker during turbulence?
The idea behind the dimming lights is to give passengers time to adjust their eyes to the lighting outside. Well, in the event of an emergency situation your eyes would need time to adjust to the darkness outside, but if they dim the lights you’ll already be adjusted to see your surroundings and respond accordingly.

What do flickering stars mean?
Atmospheric Disturbances The turbulence of the Earth’s atmosphere is caused by shifting layers of air at different temperatures and densities. The light that you see from stars gets shuffled through the Earth’s atmosphere, and you perceive this as a twinkle.
Why do lights look like they are moving?
The autokinetic effect (also referred to as autokinesis) is a phenomenon of visual perception in which a stationary, small point of light in an otherwise dark or featureless environment appears to move.
