Object alteration

An object alteration is defined as the experience of perceiving an object, objects, or entire scenes progressively warp, move, stretch, shift, or otherwise animate in three-dimensional space in a manner which can vary from subtle to extreme.^[1][2][3][4] When the person looks away or double-takes, the object is instantly reset to its original form. If the object is stared at directly again, it may begin to distort in a similar or different manner as before. The alterations do not occur in a uniform manner and cannot be reliably predicted. The intensity of the effect is often linked to the intensity and progression of the mental state that coincides with this effect.

For example, staring at an object such as a chair may cause its 3-dimensional shape to begin to drastically elongate or tilt into an exaggerated form which retains its original colours and textures.

This effect also commonly manifests as the perception of textures progressively stretching and projecting outward from the surfaces which they reside upon in the form of a detailed 3-dimensional structure^[4] 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. The textures may appear to project outwards in 3-D space anywhere between several inches to several meters in length. For example, if one stares 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,^[4][5][6] 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.^[6] They are 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.
