Why is this theory called activation-synthesis?
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.
What is the problem with activation-synthesis theory?
Dream content is more coherent, consistent over time, and continuous with waking emotional concerns than the activation-synthesis theory would predict.

What is activation-synthesis in psychology?
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.
