I can give you a hint if you want: The numbers on the clock (1, 2, 3) aren't the direct numbers that need to be entered into the combination lock. Pay attention to WHERE on the clock these three numbers are placed. The clock is empty now but usually there would be numbers on it right? The 1 written in blood indicates which number is the FIRST one for the combination lock, the 2 written in blood indicates which number is the SECOND one for the combination lock, and the same goes for the 3!! Aaaahh hope this helped, if not feel free to ask again :')
