> This, in my eyes, is the function of dreaming. To highlight our neuroses/unconscious redundant anxieties. For this reason, controlling the content of your dreams would remove their primary function.

A large percent of people are lucid dreamers up until their 20s, so there likely isn't any hugely detrimental impact over some level of control over one's dreams.

> I posit that during dreaming, the brain creates situations in which it would be wise to be unavoidant.

For the longest time, my dreams were on the exciting / dangerous side. Lots of getting shot at, lots of fighting, lots of fun, but high stress situations. I had one dream that always stood out where I was actively terraforming worlds over the course of thousands of years in an attempt to create sentient life that could fight off a slowly progressing alien wave that was sweeping through the galaxy. Lots of fun, at least for my definition of fun.

Also had a dream that took place over hundreds+ of years where I was stuck on a spaceship that thanks to relativity, had long since outlived the rest of humanity. That was a rather lonely dream.

I've also watched plenty of movies in my dreams, and listened to some amazing concerts. I always wished I knew enough about music so I could transcribe the songs after I wake up. :(

One thing that I miss now that I'm older is some of the plot lines from my dreams that had been going on for decades. It sucks to lose contact with some of the characters and places I used to visit.
