Final answer:
In chapter 29, Pharoah starts to experience nightmares while sleeping, which is shown by the narratives filled with fear and anxiety. Sleepwalking or sleep-talking as acts of dream engagement are unlikely due to the occurrence of these behaviors in non-REM sleep, as opposed to dreams which occur during REM sleep.
Step-by-step explanation:
In chapter 29, Pharoah starts to have nightmares in his sleep. This is indicated through the description of a frightened John waking up in the middle of the night, feeling a hard lump in the pit of his stomach as he reacts to a faint sound and a whisper. The anxious and strained atmosphere suggests that the event was a nightmare.
Moreover, the provided passages don't describe Pharoah engaging in sleepwalking or sleep-talking, and there is no mention of him screaming loudly. Therefore, option C) Have nightmares appears to be the correct response.
From an analytical perspective, the claim that sleepwalking and talking in one's sleep are ways of acting out dreams is unlikely because these behaviors occur during different stages of sleep. Sleepwalking and sleep-talking usually happen during non-REM sleep when the brain is not experiencing dreams, which generally happen during REM sleep.
