Answer:
Helen is taking the activation-synthesis theory perspective, while Joe is taking the wish fulfillment perspective on dreaming
Explanation:
The theory called the activation-synthesis theory states that our dreams are just a product of the activity of our brain when it is at high intensity while we sleep. This high activity triggers preset stimuli in specific regions of the cerebral cortex, which are responsible for emotions. In this case, when Helen tells Joe that his dream is just a random, meaningless by-product of REM sleep, she is relying on the activation-synthesis theory.
Joe, on the other hand, believes that his dream is an out of his mind to fulfill an unconscious wish. In this case, we can confirm that he is based on the theory made by Freud, the wish fulfillment theory, which states that dreams exist as psychic phenomena that intend to fulfill an unconscious desire of the sleeping individual.
