How is a "confused" state characterized?

A "confused" state is characterized by a slight decrease of consciousness along with incoherent thoughts. This can manifest as difficulty in concentrating, impaired judgment, and a reduced awareness of one’s surroundings. Individuals may have trouble processing information and may respond in a disorganized manner or struggle to follow a conversation. This state reflects a disturbance in cognitive function, where the person's responses may be inconsistent and they might not fully grasp the context of the situation.

The other answers describe different conditions: abnormal excitement and hallucinations suggest a state of agitation or psychosis rather than confusion; consistent sleeping and difficulty to arouse indicate more severe altered levels of consciousness, such as lethargy or a stupor; and purposely ignoring external stimuli corresponds to a state of denial or dissociation, which does not align with the characteristics of confusion. Thus, the description of the confused state aligns best with the slight decrease in consciousness and incoherent thought processes.
