How does Norman Osborn snap out of The Green Goblin?

[HrdRok12]

Spider-Man’s archnemesis The Green Goblin has become infamous for tormenting Spidey for no reason other than his sick amusement. He was revealed to be Norman Osborn, the father of his best friend Harry. Sources state that the goblin is triggered by his existence being threatened. For instance in No Way Home we saw him take over shortly after Norman realised that he was gonna be cured. The goblin didn’t like that and sprung into action. However the first time we saw Norman out or costume is the morning after Spidey stopped electro. We saw him smash the goblin helmet and run away with the goblin’s infamous cackle. So what I wanna know is how does Norman snap out of his Green Goblin persona and revert back to Norman

You know, he's something of a split personality, himself.
