For a few days I have been meditating on the Nick Bostrom's theory in my head.
I think reality is like a dream in different levels, in some you are more lost in the role of the dream, in others you are lucid and conscious. When you are aware that you are in a dream, you lose fear and can do whatever you want. I have always thought that dreams are simulations.

Dream and simulation are synonyms.

People worry a lot about whether it is possible to prove something. "Proving" something implies subjecting it to scientific reductionism, we can not prove the ultimate Truth, it is unattainable, but we can live it, we can experience it through faith, which is the infinite resource of all things.
