Object activation is defined as the experience of looking at an object and perceiving it to move, become alive, or become fully animated and autonomous of its own accord. For example, a 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 day to day life, implying that the person is experiencing a combination of both object alterations and external hallucinations being applied to their environment.
However, it is worth noting that certain activated objects 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 form. Stationary objects, such as rugs, may activate themselves and begin crawling on the floor and up onto other stationary pieces of furniture. 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.
In rare cases, autonomous entities such as shadow people may aid in an object's activation. A shadow person or other autonomous entity may pick up, rearrange, or move a stationary object in front of the observer and act as a "cause" of the object's activation.
Object activation is often accompanied by other coinciding effects such as delirium, psychosis, cognitive dysphoria, and delusions in a manner which can result in the hallucinations being perceived to have distinctly sinister and unsettling undertones. It is most commonly induced under the influence of heavy dosages of deliriant compounds, such as DPH, datura, and benzydamine. However, they can also occur to a lesser extent under the influence of psychedelics, dissociatives, stimulant psychosis, and sleep deprivation.
