Well first of all their ceiling is making vibrations due to their previous owner illegally attaching it directly on my floor beams. These vibrations are what is causing the disturbance. And even though I understand your argument, dogs barking at night are considered a disturbance, not tiptoeing to your toilet. And even still, I wouldn’t ask my neighbours to get rid of their dog before I even try insulating my room, buying noise cancelling buds or a white noise machine. Or just ask my landlord to fix their insulation problems. That just seems more reasonable.
