Dreams are basically simulations of our lives that we run, sometimes with different physical constants, resulting in different worldly behaviours. Fever dreams (not necessarily during a fever) are when we are sweeping over a range of constants, so behaviour keeps on changing.
Maybe the dreams are true reality and what you perceive as being awake is simply a faded memory of what you believe happened. After all, your memories are mostly made up anyway.

I rarely ever feature in my own dreams. Nor do people I know. My brain invents completely fictitious stories and characters, like watching a movie or a stage play.
i did not necessarily me mean our as in the person who is dreaming, our as in mostly humans, it is like a diorama we run, not exactly playing sims in our mind
According to some prominent theories, the world of our waking experience is itself a mental simulation of sorts.
There’s a related theory that dreams basically prevent this mental simulation from overfitting our experience, so our brains are always primed to accept the unpredictable.
I mean, the real world does actually exist. But we only experience a simulation of it, created by our brain based on data from our senses. So yes, we live in a simulation, but it does correspond to reality behind it.
