I started a survival world on Windows 10 but then with this problem I checked it on these other platforms and it also showed up

I started playing on normal difficulty and literally as soon as nightfall hit there was a boat a million skeletons and zombies and creepers spawn inside my house even with torches and there is no spawners nearby cuz the closest spawner is about 100 blocks away and about 30 blocks down below where my house is and they're spawning above ground

I kill them eventually and repair my house as I'll have to and then the next night after I sleep they're just spawning back all over again like they stayed there and new ones just came
