With over 60 associated symptoms,<unk>  affects the sense of vision, sensation, touch, and hearing, as well as the perception of one's own body image. Migraines, nausea, dizziness, and agitation are also commonly associated symptoms with<unk> . Less frequent symptoms also include loss of limb control and coordination, memory loss, lingering touch and sound sensations, and emotional instability.<unk>  is often associated with distortion of sensory perception, which involves visual, somatosensory, and non-visual symptoms.<unk>  is characterized by the individual being able to recognize the distortion in the perception of their own body and is episodic in nature.<unk>  episodes vary in length from person to person. Episodes typically last from a few minutes to an hour, and each episode may vary in experience. Visual distortions Individuals with<unk>  can experience illusions of expansion, reduction or distortion of their own body image, such as microsomatognosia (feeling that their own body or body parts are shrinking), or macrosomatognosia (feeling that their body or body parts are growing taller or larger). These changes in perception are collectively known as metamorphopsias, or Lilliputian hallucinations, which refers to objects appearing either smaller or larger than reality. People with certain neurological diseases have also experienced similar visual hallucinations. Within the category of Lilliputian hallucinations, people may experience either micropsia or macropsia. Micropsia is an abnormal visual condition, usually occurring in the context of visual hallucination, in which the affected person sees objects as being smaller than they are in reality. Macropsia is a condition where the individual sees everything larger than it actually is. These visual distortions are sometimes classified as<unk>  in<unk> -like syndrome" instead of true<unk> , but are often still classified as<unk>  by health professionals and researchers, since the distinction is not official. It was reported, by Lanska and Lanska (2013), that of all clinical cases, "Some 85% of patients present with perceptual distortions in a single sensory modality, e.g., only visual or only somesthetic in nature. Moreover, the majority experience only a single type of distortion, e.g., only micropsia or only macropsia." Hallucinations Zoopsia is an additional hallucination that is sometimes associated with<unk> . Zoopsias involve hallucinations of either swarms of small animals (e.g. ants and mice, etc.), or isolated groups of larger animals (e.g. dogs and elephants, etc.). This experience of zoopsias is a shared symptom of a variety of conditions, such as delirium tremens. In addition, some people may, in conjunction with a high fever, experience more intense and overt hallucinations, seeing things that are not there and misinterpreting events and situations. Depersonalization/derealization Along with these size, mass, and shape distortions of the body, those with<unk>  often experience a feeling of disconnection from one's own body, feelings, thoughts, and environment. Hearing and time distortions Individuals experiencing<unk>  can also often experience paranoia as a result of disturbances in sound perception. These disturbances can include amplification of soft sounds or misinterpretation of common sounds. Other auditory changes include distortion in pitch and tone and hearing indistinguishable and strange voices, noises, or music. A person affected by<unk>  may also lose a sense of time, a problem similar to the lack of spatial perspective brought on by visual distortion. Time may seem to pass very slowly, similar to an LSD experience, and the lack of time and space perspective can also lead to a distorted sense of velocity. For example, an object could be moving extremely slowly in reality, but to a person experiencing time distortions, it could seem that the object was sprinting uncontrollably along a moving walkway, leading to severe, overwhelming disorientation. Having symptoms of time distortion are correlated with various underlying conditions, for example, substance use, migraine, epilepsy, head trauma, and encephalitis. Regardless of an individual's disease diagnosis, time distortions are often included as a symptom associated with<unk>  since they are classified as perceptual distortions. Therefore, a person can be described to have<unk>  even if that person is experiencing time distortions due to an underlying condition.
