Though the narrator doesn’t acknowledge the possibility, it’s possible that Hempstock Farm could be both supernatural
and in the Domesday Book. The Hempstock women are clearly abnormal or supernatural in some way, so seemingly anything is possible. It’s telling, though, that the narrator only fixates on the fact that he made a friend. More important than trying to figure out how Hempstock farm works is the fact that he met a person who takes him seriously, treats him kindly, and gives him gifts.
