The Activation-Synthesis Hypothesis is a neurobiological theory of dreams. First proposed by Harvard University psychiatrists John Allan Hobson and Robert McCarley in 1977, the hypothesis suggests that dreams are created by changes in neuron activity that activates the brainstem during REM sleep.
What did Hobson and McCarley propose?
Allan Hobson and Robert McCarley proposed what is known as the Activation-Synthesis Theory. This theory states that dreaming occurs because the brain is trying to process the neural activity that goes on in our heads. … This was one of the most important theories about dreams that was ever made.
What is the main idea of the activation-synthesis theory?
The main idea behind activation-synthesis theory is that dreams are just the brain’s efforts to make sense out of meaningless patterns of firing in the brain as we sleep. Certain circuits in the brain become activated during REM sleep.

The Theory of Neural Activation This theory, proposed by John Allan Hobson, explains that, during REM sleep, the brain is attempting to make sense of the neural activity it is picking up.
What is Freud's wish fulfillment theory?
Freud’s most well-known theory, wish fulfillment, is the idea that when wishes can’t or won’t be fulfilled in our waking lives, they are carried out in dreams. Even anxious or punishing dreams have their roots in wish fulfillment, according to Freud. Dreams are fleeting.

Another theory, called the activation-synthesis theory, proposes that neurons in the brain randomly activate during REM sleep. Dreams arise when the cortex of the brain tries to make meaning out of these random neural impulses. According to activation-synthesis theory, dreams are basically brain sparks.

Freud therefore identified two types of dreams: manifest dream and latent dream. He stated that the latent dream is the real dream, and the goal of dream interpretation is to reveal it. To further elaborate on this idea, Freud proposed four mechanisms by which latent dream can be obscured.
