Answer:
(1) Sondra: Hears voices or other sounds that are not there.
(2) Bill: Delusion of control; thinks his mother plants bad thoughts in his head.
Step-by-step explanation:
(1) Sondra has auditory hallucinations, meaning she hears voices or sounds that aren't actually there in her surroundings. Her daily functioning and reality perception may be negatively affected by these disturbing hallucinations.
(2) Bill is showing signs of a delusion of control, which is the misconception that someone outside of oneself is affecting or controlling one's thoughts or behavior. In Bill's instance, despite the lack of any supporting evidence, he is adamant that his mother is purposefully implanting evil notions in his mind. Due to Bill's misconception that his mother poses a threat rather than a source of support, this hallucination can cause serious grief and strained relationships.
