In real - life, a dream house may seem perfect at first glance. But then things can go wrong. For instance, if the house is located in an area with frequent natural disasters like floods or wildfires. Even if the house itself is great, the constant threat of such disasters can make it a nightmare. And sometimes, the legal issues associated with the property, like unclear ownership history or zoning problems, can create a lot of headaches and transform the dream house concept into a real - life nightmare.
I'm not really into yaoi fanfictions, but generally, in 'dreamtale', Nightmare and Dream are two important characters. In yaoi fanfictions about them, it often explores their complex relationship in a romantic or emotional way. Writers might focus on their opposing natures, like Nightmare being more on the dark side and Dream on the light side, and how they interact and perhaps develop feelings for each other in this fictional context.
One common theme is the exploration of duality. Since Dream and Nightmare are opposites, many fanfictions explore how they are two sides of the same coin. For example, how Nightmare might have some good in him despite his dark nature, and vice versa for Dream.
One popular theme could be redemption. Nightmare, being the more 'evil' of the two in the original concept, might find redemption through his relationship with Dream. Another theme could be forbidden love, as they are on opposite sides of the spectrum in 'dreamtale'.
One great Dream Sans x Nightmare Sans fanfiction is 'The Dual Existence'. It beautifully explores the complex relationship between them. The story dives deep into their opposing natures yet shows how they are also two sides of the same coin. It has some really well - written dialogue that gives a great insight into their characters.
One common theme could be fear. Since it's about nightmare dreams, fear would likely play a big role. Another theme might be self - discovery. Maybe in the nightmare dreams, Chuck Casey discovers something about himself. Also, there could be a theme of survival, as he might be facing some sort of threat in these dreams.
