Last time my parents old house, on top walk like dino, then suddenly like drop heavy things till the ceiling and side wall literally vibrate, worse its happening in the bed room.
Go up they act sincere and concern, they even show me inside their room saying theres nothing heavy that will cause the noise.
But i knew its then cos everytime heard the dino footstep, it will be followed by toilet flushing sound ...
Initially it gets better, after some time all the noise and pattern came back as usual. So i tat time when they show me inside their bed room, i notice they are sleeping on mattress on the floor, so i remember the location, so when i go toilet or 3am, 4am, i will tie a pole with cloth at the end to prevent damaging my ceiling paint, i will walk around their bed, and poke poke the ceiling wif the pole ... Then sometimes the location where they are putting their head on and gave a good thrust.
They can control their heavy fooststep but they dun care, so whenever i hear loud bang that vibrate my ceiling or dino steps, i will poke my ceiling goig round their bed few hours later at 3am 4 am etc...'
It works perfect, they knew i was retaliating and they behave .... end up my neighbours below which i knew, politely ask me if i am hitting the wall or the floor .... I hit my ceiling, the unit below can hear the noise at the side of their wall .... thats how sound travels ...
End up i headache, i wanna retaliate my top neighbour, but disturb my neighbours below ....
I told my neighbour below wat happens, she suggest call here call there, end up all no use, the pole with cloth at the end works best.
Another one is bouncing basketball at ur ceiling .... the hard leather and hollow ball can echo and radiate the thumping and vibration for ur top neighbour to enjoy ....
Another one is more zek ark, which i dun wanna do, is poke the floor of their precious daughters room at 2am, 3am, 4am .... but i dun have to go to this extend before they behave
Talk no use one have to make them feel the pain and suffering themslves.
Argue reason no use one, some even enjoying themselves in the process as u are at his mercy and know tat u cannot do anything.
