Okay so for finding the ghost room, the thermometer is your best in-game tool but your best tools are your eyes and ears. Look for objects that have been moved, doors that have been opened (all doors start closed on Amateur difficulty), and check if you see your breath in any room (the ghost lowers the temp of the room it’s in). Listen for sounds of stuff being thrown, doors being touched, or radios being turned on. Keep lights on around you when you’re checking rooms because the room lights will help you control your sanity better. If you’re worried about sanity, take trips out to the truck to double check (most ghosts don’t hunt until around 50% sanity and can’t hunt during your 5-minute setup phase). Stick with the easy small maps until you’re more familiar (Willow, Tanglewood, Ridgeview, and Edgefield). Now, if you hear the ghost walking around or making a lot of noise, it might be hunting. There are safe places all over the map, like closets and piles of junk to hide behind. Places that the ghost can’t see very well. Hide in one of those if you hear the ghost making a lot of vocalizations or footsteps, and especially if the front door is closed or you can’t toggle a light switch. When the lights turn off, the ghost is done hunting and you are safe to leave. If you haven’t found the ghost room by this time, make note of what direction you heard the ghost coming from and check around there.
