I hope this is the right place for this.

Entoptic Imagery and Altered States of Consciousness

Entoptic images are visual effects which originate within the visual processing system of the observer. The term ‘entoptic’ comes from the Greek for ‘within vision’, indicating that the images come from anywhere within the optic system, between the eye itself and the neural cortex where signals from the optic nerve are interpreted. Since it originates within the visual system, entoptic imagery can only be seen by the observer.

Definitely some interesting stuff... Way more info and images in the article with plenty of references.

Really cool.
Some crazy theories about entheogens and entoptic images I would have never thought about visuals being projections of our memories onto eye squiggles.
