You technically can, it’s just unpleasant. No, really, sour/lumpy milk is technically more or less safe to drink- just disgusting taste-wise. The reason it doesn’t just turn into cheese is because cheese and sour cream and yoghurt are all made under more carefully controlled conditions than a half-empty jug of milk that’s left to sit in your fridge.
