Book of the dead, a possible evil dead reference?

[bronze kettle]

their is a book that spawns here called the book of the dead. has a little orange/yellow chest symbol on it when using survivor sense and once you pick it up its gone,. doesnt respawn and isnt shown in your inventory

thought another location had a connection

but it seems that this house is full of movie references

this one could be based off of the movie driller killer

this one seems like a john wick one

this one could be final destination or saw

dont know about this one

here their are candles on the floor in a ring, tried lighting them with a molotov didnt work. tried killing a zombie in the ring with fire and didnt work. tried cutting the leg off of a zombie and burning it in the circle twice for each leg, reason for taking a leg is there is one on the table

In the same room where that book is a lamp blinks in a controlled repeated pattern/maybe morse code. Would probably be worthwhile to decode.
