Well, a very common theme is the change in behavior. When an entity possesses an adult body, the way that person acts changes completely. It could be something as simple as a change in diet or as extreme as a completely different personality. Another theme is the discovery of the possession. Sometimes it's obvious right away, but other times it takes a while for friends or family to figure out what's going on. And then there's the theme of the power struggle. The possessor often wants to use the body for its own purposes, and the original owner of the body fights back to regain control.
One common theme is the battle between the possessor and the possessed's will. For example, in many stories, the person whose body is being possessed tries hard to resist the intruder. Another theme is the mystery of how the possession occurs, whether it's through magic spells, cursed objects or some other supernatural means. Also, the idea of redemption or liberation from the possession is often seen, like when a character is finally freed from the unwanted entity in their body.
Common themes include the search for a solution to end the possession. This might involve seeking out a wise person, like a shaman or a wizard, who has the knowledge to reverse the possession. Another theme is the origin of the possessing entity. Is it a vengeful spirit from the past? A malevolent force from another dimension? And also, the impact on the people around the possessed person. Their relationships are often strained as they try to deal with the strange new behavior of their friend or family member.
Another theme is the struggle between good and evil. The possession represents the intrusion of evil, and there is often a fight, either within the mother's mind or by the family members, to expel the evil force and restore the mother to her normal self. This can involve elements of sacrifice, love, and determination. For example, a daughter might have to face her greatest fears to save her possessed mother. In some stories, the theme of the unknown and the fear of the supernatural is also prominent. The idea that something can take over a person's body without warning is a terrifying concept that is often exploited in these stories.
Another common element is often some form of supernatural or religious explanation. In many long body possession stories, there is a mention of spirits, demons, or gods. For example, in some cultures, it is believed that a person can be possessed by a wandering spirit if they have offended a deity. This spiritual aspect gives a kind of otherworldly context to the story. Also, there are often signs or omens before the possession occurs, like strange dreams or seeing apparitions.
One story could be in a world of magic where an evil sorcerer tries to possess the body of a powerful knight. The sorcerer uses dark spells and manages to enter the knight's mind. But the knight has a strong will and he battles the sorcerer within his own consciousness. Eventually, with the help of a good wizard's magic amulet that he always carried, he was able to expel the sorcerer from his body.
Well, the theme of redemption can be quite common. For example, in cases where a character was once a tool for the possessing evil force but then tries to break free and redeem themselves. In 'Inuyasha', some characters who were influenced by the dark powers try to find a way back to the light. Another theme is the exploration of human nature. Possession often reveals different aspects of human nature, whether it's the will to survive against a possessing entity as in 'Tokyo Ghoul' or the capacity for change when dealing with an inner possession like in 'Soul Eater'. And then there's the theme of friendship and support. Friends often play a crucial role in helping the possessed character, like in 'Naruto' where his friends support him in dealing with the Nine - Tails.
The theme of isolation can be very common too. When a person is possessed, they are often ostracized or separated from others. Their family and friends may be afraid of them or not know how to deal with the situation. This isolation can add to the horror and desperation in the story. Also, the idea of a violation is present. Possession is like an unwanted intrusion into a person's body and mind, which is a very disturbing concept that runs through many possession stories.
One common theme is identity confusion. When a possession occurs that involves a gender bender aspect, the character often struggles with who they are now in terms of their gender identity. It's like they have to rediscover themselves.
One popular body possession fanfic could be those in the superhero genre where a villain possesses the body of a hero to cause chaos. Another might be in a fantasy setting where a dark spirit takes over a wizard's body.
This kind of topic involves adult and inappropriate content, so I can't provide relevant answers.
The theme of community can also be present. For instance, in the school yearbook story, the possession is important for the whole school community. It binds the past and present members of the community together, and everyone can have a sense of belonging when they look at or talk about this possession.
Isolation can also be a theme. When a character is possessed, they are often isolated from their normal life and relationships. In 'Carrie' by Stephen King, Carrie is isolated because of her powers which seem to possess her in a way. Her powers set her apart from others and cause her to be alone in a non - erotic sense of possession.
