One common theme is secrecy. In these novels, characters often keep their obsessions hidden, which adds to the mystery and tension.
Another theme is the loss of self - control. The characters' obsessions overtake them, and they may do things they wouldn't normally do. For example, in 'Gone Girl', the characters' actions spiral out of control due to their obsessions. Also, psychological turmoil is a big theme. The characters are often in a state of inner chaos because of their obsessions, like in 'The Girl on the Train' where the main character's mental state is greatly affected by her fixation on the couple she watches.
Power dynamics can also be a theme. Sometimes, the object of obsession has power over the obsessed person, or vice versa. And there's often a sense of the past haunting the present. In 'Sharp Objects', the protagonist's past obsessions and traumas keep resurfacing and influencing her current situation. These themes work together to create the dark and alluring nature of 'dark obsession novels'.
