the brain is a hodgepodge of neurons evolved over a stupendous amount of time to deal with so many different things throughout the timeline of our ancestors, i think it's perfectly reasonable to just assume memories of dreams are left around in some neurons and when the same processes start before falling asleep the remaining parts of the memories just happen to get accessed again.
I kinda assumed that
Dreams usually make little sense - one can fly, punches don't work, you have no pants... because the parts of our brain that make reason and logic are sleeping.
We forget dreams because the waking brain can't make sense of them, so the thoughtsare discarded or ignored.
So, as your brain goes to the sleep state, the reality dissolves to dreamscape, allowing you to remember the nonsensical experiences.
eh i don't think most of that is true, pretty sure the dreams you remember are only the insane ones because you actually make an effort to remember them when you wake up.
To my knowledge dreams exist because our brains use the downtime of sleep to run simulations so we can practice stuff and sort of prepare for unexpected situations.
i think the reason we forget dreams is just because there's no point in keeping it around, the brain has already benefited from the dreams and it'd be unfortunate if we mistook a dream for reality and screwed something up because of that.
