Character mistake: Claire's behavior makes no sense and is intirely implausible and unrealistic. For example: Whenever Claire talks about the ghost, she never mentions any of her compelling observations. When she tells Norman about the seance, she incorrectly says that nothing happened. Claire wakes Norman up to look at the Feur driveway after the apparent body-bag is already in the closed trunk. What did she want him to observe? A car? An empty driveway?
Suggested correction: People already wonder if Claire is unstable right now. Her daughter left for college. She sometimes takes anxiety medication (she told the therapist). Her husband is a practical, realistic scientist. Those could all be reasons why she thinks that her observations will be dismissed. Also, reasons to not say much about a seance. Regarding the car, Norman didn't move fast enough see everything before Mr. Feur left. Again, he might simply think Claire is imaginative and nosy at this time.
