One theory is dreams are you brain doing maintenance on memories. Doing a defrag, cleaning dust, something like that, but we don’t really know for sure. You briefly relive those memories. Another part of the brain sees those flashes of memories and tries to make sense of these, like a narrator that forgot the script at home. And that’s what you experience as a dream. You just had a strong response to this particular memory.
