According to the activation-synthesis hypothesis, it should be possible to predict (with better than chance accuracy) the content of a person's dreams if we know what information about the person?

Stimuli currently acting on the body and areas of spontaneous brain activity.
Stimuli currently acting on the body and areas of spontaneous brain activity.
According to the activation-synthesis hypothesis, what do dreams reflect? Unconscious motivations and emotions. Experiences that have been part of the species' evolutionary history. An imbalance among hormone levels. The brain's attempt to make sense of spontaneous neural activity

If we compare either different species or different ages, what trend emerges? The more activity during wakefulness, the higher the percentage of REM sleep. The more activity during wakefulness, the lower the percentage of REM sleep. The less total sleep, the higher the percentage of REM sleep.
