Is it normal that i could not sleep properly because of this?

Last night I couldn't sleep to the point I had to open the windows to see what was happening, I could hear a man and woman shouting, the man punched the woman and then she starts asking why he did that not long after she had bursted into tears ( I could only assume that it was probably some sort of abusive relationship or something but I couldn't tell if it was one ), next thing that happened police got involved and everyone came out of their houses to see what had happened but what made me kinda sad was when the woman ran off in tears.
