Answer: (A)

Verified step by step guidance

1. Understand the characteristics of REM sleep: REM (Rapid Eye Movement) sleep is a stage of sleep where dreaming is most vivid and bizarre, often involving unusual scenarios that seem normal to the dreamer.
2. Recognize the lack of awareness in dreams: During REM sleep, individuals typically experience a lack of awareness that the dream content is odd or unrealistic, which aligns with Janice's experience.
3. Differentiate REM sleep from non-REM stages: Non-REM sleep stages (Stage 1, Stage 2, Stage 4) are generally associated with less vivid dreaming and more realistic scenarios.
4. Consider the physiological aspects of REM sleep: REM sleep is characterized by rapid eye movements, increased brain activity, and temporary muscle paralysis, which allows for vivid dreaming without physical movement.
5. Conclude that Janice's dream characteristics align with REM sleep: Given the flying dog and moving sidewalk, Janice's dream fits the profile of REM sleep, where bizarre and vivid dreams occur.
