Gingerbread people are bestowed life by magical bakers. The same magic could be used to bring a gingerbread house to life it just would be in a nightmarish situation since houses don't have many moving parts besides doors and shutters. Most magical bakers would never do something like that because magical bakers are bestowed their powers by the love of the people they feed. People who find joy in feeding others are rarely ever evil and therefore would never create a nightmarish monster gingerbread house.

This doesn't really have anything to do with the vaccine. I haven't had a chance to get mine because work is a never-ending nightmare but holy shit fever dreams are one of my favorite things. They are always so intense. I specifically remember one where these giant fish called dipsticks (they looked like giant dipstick candies but black and oily like a cartoon whale) would breach straight up out of the water and then slam onto the water with a loud slap. I'd always get a little too close to the lake and get dizzy and start rolling into the water and my friends wouldn't help me when I'd reached out for them so the fish would eat me and then I'd wake up. I would read a book of people describing fever dreams.
