Rem sleep is pretty bizarre. I feel like science really doesnt understand or cant explain why ir occurs. Maybe our brains are just computers and they get info downloaded into them when we go to sleep. Perhaps the sun has a massive alien master computer inside and what we call radiation is the bits of info sent out to program us and give updates. I cant really explain why i have random shit pop into my head moment to moment.
