Question

Q- Why & How do we Dream?​

Answer 1

Explanation:

Dreams are hallucinations that occur during certain stages of sleep. They're strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health.

Answer 2

Dreams are patterns of sensory information that occur when the brain is in a resting state – as in asleep. It is generally assumed that dreams only occur during rapid eye movement (REM) sleep – this is when the brain appears to be in an active state but the individual is asleep and in a state of paralysis. But studies have shown that they can also happen outside of REM.

Research from sleep studies, for example, shows that REM-related dreams tend to be more fantastical, more colourful and vivid whereas non-REM dreams are more concrete and usually characterised in black and white. Recent studies on dreaming show that during a dream (and in particular a REM-related dream) the emotional centre of the brain is highly active whereas the logical rational centre of the brain is slowed. This can help explain why these dreams are more emotive and surreal.
