For instance: a small child around five years of age dreams she is being chased by a bear, or a wolf, or a tiger (saber toothed or other wise), or any other predator. I think her brain is running a test of the situation that her cave man ancestors may have had to face. I think it helps to hardwire that fight or flight reaction in the face of danger. Now, when this child grows older she starts to have more relevant dreams to her current stresses of life. When she is starting school she starts to have dreams about the tests. Failing them, not finishing, stuff along those lines. I think that these dreams are preparing her for school life and the possible out comes of tests. When she's even older she has dreams about crashing her car, losing her phone, going bankrupt, failing to pay taxes on time, other adult things that her brain is preparing her for. THough this is just what I think about those incredibly vivid dreams where the fear and emotions are real.
If this part is accurate, then my brain spent a lot of time preparing me for crawling through overgrown, abandoned gardens with rose bushes and driving in a rental car with my family at night in a strange country with only the sound of static and these unnatural glowing hut things. Those are the only dreams I remember, except for a dream about skateboarding.
In my opinion, the brain does test runs, like you said, but not just like what to do in different situations but also just testing and different functions of the brain and such to make sure everything is working properly and not unused for a long time. I've heard the brain also processes information learned during the day and moves things to long term memory while asleep, so maybe dreams are one way the brain sorts important memories from irrelevant ones or dreams use parts of the brain that weren't used during the day to just kinda refresh them.
