Common themes include transformation. When they come back, they are not the same as before. It could be a physical, mental, or spiritual change. Another theme is the blurring of the boundaries between life and death. These stories play with the idea that death may not be as final as we think. There's also the theme of discovery. They might discover new powers or insights about themselves or the world around them during or after their 'death' and 'return'. For instance, in some tales, a character comes back with the ability to see ghosts or predict the future, which was not possible before their near - death or death experience.
Most of these stories are fictional. There's no scientific evidence to support the idea of actually dying and coming back in the way these stories often portray. It's often a concept in horror, supernatural, or very imaginative fictional genres.
One possible interesting plot could be Hermione dealing with her past traumas and growing stronger as she comes back to herself. Maybe she rediscovers her love for magic in a new way after a difficult experience.
Besides the main trio, Luna Lovegood could be a character in this fanfiction. Luna has a unique perspective on things, and she might be able to help Hermione in her journey of self - discovery. Also, some of the Slytherin characters like Draco Malfoy could be involved. Maybe Draco has some information or experiences that are relevant to Hermione's situation, and their interactions could add an interesting dynamic to the story.
Often, when an ex comes back, it could be due to loneliness. They might have been on their own for a while and remembered the comfort and familiarity of the old relationship. However, it's important to be cautious. Just because they're back doesn't mean things will be the same. There could be unresolved issues from the past that might resurface.
One dumper coming back story could be that the dumper realized they made a huge mistake after leaving. They might have thought they could find someone better but then found out that the person they dumped was truly special. For example, a guy dumped his girlfriend because he was attracted to someone else at work. But after a while, he saw that the new person was just interested in his money and status. Then he remembered all the genuine love and care from his ex - girlfriend and came back to her, begging for forgiveness.
One ex coming back story is that my friend's ex returned after a year. They had broken up due to long - distance issues. But the ex got a new job in the same city and reached out. They started as friends again, slowly rebuilding trust and now they're back together, stronger than before.
