Final answer:
Jennifer had a lucid dream, which means she was aware that she was dreaming and could control the content of her dream, a concept supported by the activation-synthesis theory and thoughts on protoconsciousness.
Step-by-step explanation:
Jennifer's experience with a lucid dream implies that she was aware that she was dreaming during the dream state. Dream researcher Rosalind Cartwright found that dreams might reflect significant life events important to the dreamer, with her empirical study showing a correlation between daytime thoughts and dream content. Activation-synthesis theory by neuroscientist Alan Hobson proposes that dreams are our brains making sense of neural activity during REM sleep. Additionally, Hobson suggests that dreams may be a form of protoconsciousness, constructing a virtual reality to help us in wakefulness. John Hobson cites lucid dreams research to understand the general nature of dreams better, where a person knows they're dreaming and can sometimes control its content.
