Memory consolidation is indeed a possible explanation, but there’s no single widely accepted theory on why we dream, only many competing theories at the moment with various levels of data to support them. It’s also possible that dreams serve multiple roles in brain health, both physiological and psychological. https://en.wikipedia.org/wiki/Dream#Function https://en.wikipedia.org/wiki/Dream#Function > also, i don't think it's noise. It's injecting full scenarios to see how the brain works with it I don’t know... my dreams don’t usually seem constructed as a scenario. They seem totally random, moving from random encounter, scene etc, completely unrealistic in many instances. Cars with no front seat, buildings that don’t have physically possible layouts, words that are unreadable, etc. It sure feels like a lot of noise or random crap that somehow my brain is trying to make sense of. To me the “scenario” feels like fitting something plausible to the random data of the dream.
