After images
{{#ev:gfycat|https://giant.gfycat.com/PepperyMedicalAfghanhound.webm%7C400x225%7Cright%7CAfter images by StingrayZ - This image serves as an accurate portrayal of the commonly experienced psychedelic effect known as after images. There is also a significant amount of visual drifting within its background.|frame}} After images (also known as palinopsia) are visual perceptions which continue to appear in one's vision after exposure to the original image has ceased.[1][2][3] A common form of after image is the bright glow that seems to float in one's vision after looking into a light source for a few seconds. This effect is similar to tracers, but differs in that it does not create smooth blurs behind moving objects.
During hallucinogenic experiences, still overlayed images of moving objects are commonly left in place of where the object once was.[4][5][6][3][7][8] This creates a series of overlayed images across one's visual field which become less distinct the further away they are from the moving object's current position. Another manifestation of this effect can be described as being able to see the external environment for several seconds after one closes their eyes before it gradually fades away.
After images are often accompanied by other coinciding effects such as tracers[5][9][10] and drifting.[4] They are most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.[11] However, trailing effects have also been experienced with other drugs of a very different pharmacology, such as GABA potentiators.[7]
