Yes. Bates Motel is based on the novel 'Psycho'. The novel provides the foundation for the story of the motel and its owner, Norman Bates. In both the novel and the TV series, we see the complex and often disturbing relationship between Norman and his mother. The TV adaptation takes the basic concepts from the novel and brings them to life in a more visual and extended way, exploring different aspects of the characters and their motives in greater detail.
It might be a description of a person in a story where the focus is on their physical feature (the big booty) and their action of going to the motel. It could be a stranger who the storyteller witnessed going into the motel, and they decided to create a whole story around this one sighting.
I'm not aware of any specifically 'famous' wife in motel stories in a general sense. Most stories like this are personal experiences of ordinary people. However, in literature or movies, there might be some stories that involve a similar setting of a wife in a motel which could be interpreted in different ways depending on the plot.
One possible back story is that the motel was built on an ancient burial ground. Native Americans or other early settlers might have been buried there. Their disturbed spirits haunt the motel. Lights might flicker and objects move on their own as a sign of their presence.
Yes. It draws inspiration from the character Norman Bates in Psycho. While Psycho was a fictional work by Alfred Hitchcock, Bates Motel expands on the backstory of Norman Bates, his relationship with his mother, and the motel itself. It gives more depth and context to the rather mysterious and creepy world that was first introduced in Psycho.
Definitely not. Bates Motel is a work of fiction. The story and its elements were crafted in the imagination of the creators, not based on any actual events or people.
