Oh that's a bit creepy TT :/

My worst neighbours were in a block of four units - I was bottom right, they were top left, so thankfully as far away as possible! Though we did all have doors leading to the centre stairwell. They were small 2 bed units, but they had a couple and their small child (maybe one year old) there, his brother and his mum, plus regular visitors.

They were into drugs and always very noisy but one night had us barracading the doors. It started at about 11, and there was a lot of screaming from all living there, a lot of death threats. Suddenly we heard doors bursting open, running down the stairs, the young mum started screaming so loudly. Thankfully the police weren't far away, but apparently the dad had stabbed his brother and was threatening everyone else. Not a good night for sleeping! There was still blood in the stairwell and on the concrete outside the next day. Thankfully they were evicted very soon after!
