Magnification by StingrayZ - This is an animated example of the common psychedelic visual effect known as magnification. There is also a significant amount of visual drifting present within the animation.

Magnification can be described as the experience of distant details within one's visual field appearing closer and more "zoomed in" than they actually are due to both visual enhancements and hallucinatory effects.[1] This can give one the perception that they are seeing objects from greater distances than is usually possible within everyday life.

At its lower levels, this can allow people to see objects that are within reaching distance as closer than they really are, resulting in the perception that there has been a general enhancement of visual capabilities.[1] At its higher levels, this can induce the perception of seeing objects as if they were right in front of the user across vast stretches of distance. These distances can range between several feet to hundreds of meters. Since this is most likely a physiological impossibility, it suggests that higher level magnification may actually be a seamless hallucinatory state in which the details of distant visual input are predictively simulated in a realistic and convincing manner.

It's worth noting that this effect is considerably more likely to occur if a person spends extended periods of time staring at an object or scene within the distance.

Magnification is often accompanied by other coinciding effects such as acuity enhancement and pattern recognition enhancement. It is a rare effect that is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
