How does your setting affect your story’s mood?

Mostly it takes place in an old church. A lot of the time the main characters are there at night so it sets the mood as creepy and more reasons for this are
* Someone broke in twice
* The first break in there was a bloody sharp hole in the glass and they heard noises
* The second break in Max found The Hoff laying on the floor twitching
* Police showed up and investigated b/c of the stolen letters and The Hoff
* There is a large balcony that overlooks the whole church
* The balcony rails are loose and creaky
Those are just some main reasons for why i think the church makes the setting creepy. They make it creepy b/c when you think of creepy, some things that would qualify are
* A hole in the glass door with blood
* Breaking in
* Police investigation
* Stolen letters
etc.
