I have one neighbour that stay upstair and will go crazy and running/stomping hardcore during night around 1am.
One time the guy staying downstair come to my unit and ask me to stop making loud noise, I told him it was come from above.
Not sure what's the issue of the noise maker my best bet is some kid with ADHD, anyway I'm moving out soon to the highest floor.

Yeah mine too 2 floors above me

my case, i always hear someone scratching the floor the unit above me, during midnight. but i'm assume MAYBE they have a dog, some dogs have habit scratching floor when they are bored.

Well, i'm used to be a dog owner, so i just bear with it. I dont care about the owner, but i dont want to cause trouble to the dog. Later complain, the one suffered is the poor animal
