Insomnia specifically refers to a complaint related to the quality of sleep. Individuals with insomnia may experience trouble falling asleep, staying asleep, or waking up too early and not being able to return to sleep. This results in a perception of poor sleep quality, leading to daytime impairment or distress. The core characteristic of insomnia is the subjective experience of dissatisfaction with sleep, which affects one's overall well-being and functioning.

The other options do not accurately represent insomnia. Challenges with auditory perception relate to difficulties in processing sounds, which is not connected to sleep disorders. Difficulty in maintaining attention can be a symptom of various conditions, including insomnia, but it is not what insomnia itself describes. A condition of excessive dreaming, while potentially linked to certain sleep disorders such as REM sleep behavior disorder, does not pertain to insomnia, which focuses on inadequate sleep quality rather than excessive dream activity.
