Dreams are weird

I read on qoura that the brain actually synthesises and analyses information and memories while in sleep.
So maybe that's why we see weird dreams connecting random people and places together. The interesting thing to note is that the dreams are generally populated with common people we know and common places. I see my family, friends, my home, school etc.

Anyways I seem to have forgotten the dream I had today but I remember that I did some kind of violence in this one too. Very weird. Why am I so violent in my dreams. Since I am so calm (?) In real life, such dreams do seem totally weird. Maybe they are not supposed to be analyzed.
