Transformations are the experience of a perceived visual metamorphosis that specific parts of one's external environment undergo as they shapeshift into other objects. For example, people who experience this effect will often report seeing parts of their environment shifting into completely different things. These transformations have a huge variety of potential artistic styles and differing levels of detail, realism, and animation.
These hallucinations are progressive in nature. They form from patterns or objects and their appearance fluidly drifts into an entirely new form over several seconds. This is caused and enhanced by a separate visual effect known as increased pareidolia, which can cause vague stimuli and objects to transform into incredibly detailed versions of what they were already perceived as.
At lower levels, the process of transformations can require a minimal amount of focus and concentration to sustain. Losing concentration for an instant can cause the image to fade away or shift into another image. Holding the eyes still will usually increase the intensity of the progressive transformation. However, this becomes completely unnecessary at higher levels.
It is worth noting that the content, style, and general behaviour of a transformation is often largely dependent on the emotional state of the person experiencing it. For example, a person who is emotionally stable and generally happy will be more prone to experiencing neutral and interesting transformations. In contrast, however, a person who is emotionally unstable and generally unhappy will be more prone to experiencing sinister and fear-inducing transformations.
Transformations are often accompanied by other coinciding effects, such as drifting, increased pareidolia and external hallucinations. They are most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline. However, they can also occur under the influence of deliriants such as DPH, datura, and benzydamine.
