[Vampires] If a vampire cannot enter someone’s home unless they are invited in, where is the line drawn on “home?”

-Traditional House.      
-Pre-fabricated house.    
-Apartment\Condo.      
-Trailer.     
-Tiny Home.     
-Camper/RV.      
-Furnished Storage Unit.     
-Tent.      
-Refrigerator Box.     
-Lean-to.      
-Cave.     

At what point is a Vampire free to just approach and snack on an unsuspecting victim?

A home is where a person lives. The “threshold “ is what keeps the supernatural out. The threshold is a magical energy field that weakens any supernatural being that crosses it without the free pass of an invitation. The threshold is strengthened by positive emotions over time, so its power is more determined by the dwellers than the structure.
