This is assuming you're playing this game in standard mode, not the daytime which chops off the remaining time you spent on night avoiding the hostile but I decided that playing the mode that allows nighttime is better in my opinion. Nighttime is where the creature will try to catch up to you but you got the bed to use for various reasons, luckily the creature is just one of those typical AI where it is never intimidating but you know how it goes it's a walking sim but Slenderman.
