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 hormone is released during REM sleep?
But during REM sleep, the thalamus is active, sending the cortex images, sounds, and other sensations that fill our dreams. The pineal gland, located within the brain’s two hemispheres, receives signals from the SCN and increases production of the hormone melatonin, which helps put you to sleep once the lights go down.
What is rapid eye sleep?
REM stands for rapid eye movement. During REM sleep, your eyes move around rapidly in a range of directions, but don’t send any visual information to your brain. That doesn’t happen during non-REM sleep. First comes non-REM sleep, followed by a shorter period of REM sleep, and then the cycle starts over again.
Can dreams come true in real life?
