Not having frequent fantasies was not necessarily a sickness. In many novels, this kind of fantasy scene was a very important element that could help the author construct the story plot and the emotions of the characters, enhancing the atmosphere and emotional expression of the novel.
If this fantasy activity affects your daily life and work efficiency or makes you feel anxious or uneasy, you may need to seek professional help. Some mental health problems such as anxiety and depression can cause similar symptoms. If you feel uncomfortable or have doubts, it is recommended to consult a professional doctor or psychologist.
It might be a book if it focuses more on the detailed inner thoughts and psychological analysis of the person having murder on their mind, as books can often delve deeper into such aspects. However, if it's more about visual impact and a more streamlined narrative, it could be a movie. Without more information, it's hard to tell for sure.
There were many mind-blowing suspense movies such as The Prestige, Inception, Shutter Island, Se7en, and so on.
TV series such as Veronica Mars, Westworld, Sherlock Holmes, and Doctor Who were also good choices.
For movies, try Memento, Identity, Mulholland Drive, The Butterfly Effect, Inception, and so on.
