Well, what is it? - If you shine a light into the window when Nightmare Freddy is ready to appear in the window, then he will not appear and will leave, for me it was even a surprise that this can be done, as you already know, when Nightmare Freddy appears in the window, you need to shine a light on him and he will leave, but is it possible to make it so that he always does not appear in the window, what should be done?: you need to wait until Nightmare Freddy laughs twice, and shine a light into the window in time, then he will not appear and will leave, he gives about 1.5 seconds to have time to shine a light into the window and make him leave, and you can do this constantly until you pass the night.
