This is what Wikipedia says about Phosphenes:

A phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye. [...]

Phosphenes can be directly induced by mechanical, electrical, or magnetic stimulation of the retina or visual cortex as well as by random firing of cells in the visual system. Phosphenes have also been reported by meditators (commonly called nimitta); people who go for long periods without visual stimulation (also known as the prisoner's cinema); or those who are using psychedelic drugs.

The most common phosphenes are pressure phosphenes, caused by rubbing the closed eyes. The pressure mechanically stimulates the cells of the retina. Experiences include a darkening of the visual field that moves against the rubbing, a diffuse colored patch that also moves against the rubbing, a scintillating and ever-changing and deforming light grid with occasional dark spots (like a crumpling fly-spotted flyscreen), and a sparse field of intense blue points of light.
