I don't want to cause a huge problem

I live in an apartment. And as some of yall know apartments can have thin walls.

It isnt a huge building. It is a six plex (is that even the right term?!) There are 6 apartments in our building. And the way it's set up is there is a main staircase in the middle of building. Each floor has two units - one on each side of the staircase! Basically there is a left side and a right side of the building. You have 1, 3, 5 stacked on one side and 2, 4, 6 stacked on the other side!

Ok phew. Painful.

I am right in the middle - one unit above me and one unit below me!

The issue here is the unit above me. I don't really know them. We say hello in passing and have small talk. They seem pleasant enough. But in more recent weeks, I've noticed there has been a lot of yelling, screaming, stomping, banging, and crying. Usually at night like weird times between midnight and 2AM. Half the time I hear portions of their conversations. And there is a lot of rage.

I have heard tons of swearing accompanied with the crying and banging and screaming. And of course once that starts with the adults, the kids wake up screaming and crying and it always usually ends with someone leaving, sounds of glass breaking, thuds.

I cant make assumptions because I've never seen anything. But in all honesty, it sounds like they're beating on each other and bodies being shoved into walls, along with running after people and again things hitting the ground or walls and breaking.

Would you say something? Do something? Call somebody? I mean I dont know what's really going on but it sounds shitty from my end. Thoughts?
