06:20 - 06:42 and 08:08 - 08:12 ---- Lol, it's how it was programmed. Whenever you hide in the locker, both the audio and the running animation of the chaser automatically gets halted (which is why you suddenly don't hear anything from your hiding place). And by the time you come out, everything continues where it left off. It's as if it turned into a statue while you're hiding. XDD
