Infinite Horror

Every hour, the monster your parents locked you in comes to your room. The monster is a ghost, so it can walk through walls. You are trying to survive from 10:50 p.m. to 6:00 a.m. The monster is afraid of bright light, so before it enters your room, you can turn on the light and the monster will linger and disappear for a while before you turn the light off again. But you have a limited battery for the lights. If the monster gets into your room, you have to hide in the closet or under the bed. But if you're hiding, you have 12 seconds to die of fear, which is either under the bed or in the closet. Good luck
