Two thing:

1, mistletoe? Was unaware of that lore.

B, when I worked nightshift security, I wrote an urban fantasy novel (that has since been lost :( ), in the form of security log entries about a guard working at a warehouse in a world with ooky spookies everywhere. Tons of funny shit, but my favorites were the feral werewolf pups that would occasionally get inside, and had to be scared off with the vacuum cleaner.

Also, the vampires who were sitting shiva for themselves.

The ghosts who were haunting the warehouse, but only on weekends and holidays, as a vacation.

I need to rewrite it. It was honestly some of my best writing
