There's a pattern that you can do which is you have to check cam 10 and the meet freezer camera just check those two and you should be fine and the way you can tell if classic oswald is coming is if you hear a loud bang and you can see him rush to your office and I haven't tried this but I recommend that you either hide under the desk or turn off the power and you should be fine and I hope this is helpful on how to get through night 5 bud
