Which of the following is a common symptom of schizophrenia?

Loss of contact with reality is a hallmark symptom of schizophrenia, often manifesting as delusions or hallucinations. These individuals may experience significant distortions in their thoughts and perceptions, leading to a detachment from what is considered real. This can result in difficulties distinguishing between what is a true experience and what is a symptom of their condition.

In the context of schizophrenia, this loss of reality perception is crucial for diagnosis and understanding the impact of the illness on an individual's ability to interact with the world. While increased sociability, high energy levels, and heightened sensory perception may occur in other contexts or conditions, they do not represent the primary characteristics associated with schizophrenia.
