Most people see splashes of colors and flashes of light on a not-quite-jet-black background when their eyes are closed. It’s a phenomenon called phosphene, and it boils down to this: Our visual system — eyes and brains — don’t shut off when denied light.
Are Phosphenes dangerous?
In most cases the phosphenes are harmless, but if they are recurrent, you have to pay attention, since they can be a symptom of a more serious illness. Phosphenes are the result of an irritation in the retina that, when it happens, makes an impulse that is perceived as a light.
What does it mean when you see lights when you close your eyes?
These small lights are usually phosphenes, a visual phenomenon caused by mechanical stimuli resulting in pressure or tension on the eye when the eyelids are closed. The internal lining of the eyeball is called the retina.
Why do I see flashes of light at night?

Dehydration, stress, lack of sleep, caffeine and certain foods are typical triggers for ocular migraines. When someone describes their flash stemming from only one eye and it is a quick flash usually only seen in the dark almost like a flash from a camera then I often attribute this to the vitreous gel.

Why do I see weird things when I close my eyes?
Closed-eye hallucinations are related to a scientific process called phosphenes. These occur as a result of the constant activity between neurons in the brain and your vision. Even when your eyes are closed, you can experience phosphenes. At rest, your retina still continues to produce these electrical charges.
