A good theme could be the idea of a hidden underworld. A place beneath our world filled with monsters and terrors. Another is the theme of a death omen. Strange signs that predict someone's death. Also, the theme of a haunted carnival. The bright colors and happy facades hiding dark secrets and evil entities.
Sure. 'The Haunting of Blackwood Manor' is a great one. It gives the idea of a spooky, old manor filled with secrets and ghosts. Another could be 'Shadows in the Attic', which makes you think of something lurking in the dark, dusty attic. And 'The Cursed Forest' is also good as it implies an area filled with danger and the unknown.
Midnight's Scream. It makes you think of something terrifying happening in the dead of night when people are most vulnerable.
How about 'The Creeping Fog'? Fog can hide things and create an atmosphere of unease. 'The Malignant Presence' is another great title. It implies there's something evil and present. 'The Unseen Terror' is also a good title as it makes the reader wonder about the terror that they can't see but know is there.
Eternal Nightmare. It conveys the idea of a never - ending horror, something that the characters can't escape from. Just the thought of an eternal nightmare is terrifying.
Blood Moon Rising. The image of a blood - red moon is often associated with bad omens and horror in many cultures.
Eternal Nightmare. This name directly conveys a sense of never - ending horror, like being trapped in a nightmare that just won't end. It can set a very dark and disturbing tone for the story.
Eternal Darkness. It represents a never - ending, all - consuming darkness that could be a physical place or a state of mind. In horror, the unknown in the dark is often a source of great fear.
Nightmare at Elm Street Cemetery. Elm Street is a common name that can add a sense of familiarity, but when combined with 'cemetery' and 'nightmare', it becomes a very horror - inducing title. Cemeteries are places filled with the dead, and nightmares are terrifying experiences, so this title sets a great horror mood.
'Discovery' can be a theme. A young butterfly might be exploring the world for the first time, discovering new flowers to feed on, new places to rest. This can be a metaphor for a child's discovery of the world around them, full of wonder and new experiences. For instance, the butterfly could find a hidden meadow full of the most delicious nectar and learn about the importance of exploration.
One theme could be body snatchers. Imagine a town where people start disappearing at night and are later found acting strangely. It turns out that their bodies have been taken over by some otherworldly beings. It creates a sense of paranoia as you can't trust anyone around you.
