Explanation:

According to the passage, Aurelia has been locked up in a dark room for four days. The purpose was to study sensory deprivation and its effects. As a matter of fact, studies about sensory deprivation have shown that just fifteen minutes of such deprivation (putting on blindfolds and muffling the ears) would be enough to cause the person to hallucinate. The hallucinations are caused by the brain's misunderstanding the source of sensory input. Besides hallucinations, other effects of forced sensory deprivation are anxiety and depression.
