Object alterations can be described as the experience of perceiving textures, external objects, and scenes to be progressively warping, moving, stretching, animating, and shifting in their structural form in a manner which can vary from subtle to extreme. When one looks away from the object or texture being distorted the object retains its original shape until it is looked at directly once again, whereafter it begins distorting in a similar or different manner. The manner in which the distortions occur is not uniform and cannot be reliably predicted. The intensity of the effect is often linked to the intensity and progression of the mental state that precludes this effect.
For example, when staring at an object such as a chair its 3-dimensional shape may begin to drastically elongate or tilt into an exaggerated form which retains its original colours and textures.
Another common manifestation of this effect is the perception of textures progressively extending and stretching outward from the surfaces which they reside upon in the form of a detailed 3-dimensional structure somewhat similar to complex, opaque, and solidified smoke. These structures usually maintain a size which is consistent with the width of the texture it is extending from. They can also range from anywhere between several inches to several meters in length. For example, if one is staring at a painting on the wall it may extend in one direction on a 2-dimensional plane until the observer looks away.
Although this subjective effect component is categorised as a visual distortion, it is likely an indirect result of external hallucinations being applied to objects within the user's environment occurring in a manner which does not introduce new data, but simply alters the perception of a 3-dimensional structure's content.
Object alterations are often accompanied by other coinciding effects such as delirium and psychosis. It is most commonly induced under the influence of heavy dosages of deliriant compounds, such as DPH and datura. However, they can also occur under the influence of stimulant psychosis and sleep deprivation.
Main article: Object activation
At the extreme end of object alterations, objects may become so fully animated and autonomous that it becomes debatable whether or not the component is merely a visual distortion, as it starts to take on the qualities of a standard hallucinatory state.
This distinct effect, called object activation, occurs when one looks at an object and the object moves, becomes alive, or becomes fully animated of its own accord. For example, if one is looking at a microwave the door may open and close on its own or a cup on the table may start to slide or tilt over. The "activated object" usually moves in a familiar way that would happen in everyday life, furthering the point that the brain is having external hallucinations in one's environment.
However, it may also perform actions which are completely unrealistic. For example, an item of furniture may appear to disassemble into many floating complex rotating sections before reassembling into its previous state. These hallucinations usually only occur when one looks directly at an object for an extended period of time and are rare and extreme signs of an advanced hallucinatory state.
Compounds which may cause this effect commonly include:
Benzydamine, Datura, DPH
