I barely remember this, it was most likely from some horror series like gosebumps or are you afraid of the dark or something else from the 90s, but this was the plot:>brother and sister go to this boarding school>the shool doesn't have a bell, but some low frequency buzz sound instead for whatever reason>some dude is playing some gameboy and it gets confiscated>then for whatever reason, bot brother and sister get punished by the headmaster/teacher>they are brought to some basement, where a lot of remains of previous students are on the floor (some clothes/shoes stuff)>the basement had a monster, which was the mother of the lair or something>the staff was actually monsters/aliens>they somehow realize they can't stand high frequencies, so they use some music player against the monster>the monster dies and they leaveMaybe I'm misremembering some stuff, but that's how I remember it, and I can't find it.
