Some cool titles could be 'The Haunting of Blackwood Manor'. It gives an immediate sense of a spooky place being haunted. Another one is 'The Shadow in the Cellar'. It makes you wonder what kind of shadow lurks in a usually dark and creepy cellar. And 'Midnight's Whisper' also works well as it creates an atmosphere of something mysterious and perhaps sinister happening at midnight.
Sure. 'The Ghostly Bride'. This title invokes the image of a spectral figure of a bride, which is often a very spooky concept in horror. 'The Curse of the Ancient Tomb' is also good. Ancient tombs are full of mystery and the idea of a curse makes it even more horrifying. 'The Werewolf's Lair' is another cool title as werewolves are classic horror monsters and the idea of their lair is a scary thought.
The Haunting of Blackwood Manor. This title gives a sense of mystery and fear as 'haunting' implies something spooky going on in the manor. The name 'Blackwood' also has an eerie feel to it.
Well, 'Midnight's Scream', 'Eyes in the Dark' and 'The Deadly Whispers' are really good horror story titles. They play on common fears like the unknown that lurks in the darkness and the sense of something being not quite right. For example, 'Midnight's Scream' makes you think about something terrifying happening in the middle of the night when people are usually most vulnerable.
For short horror stories, 'The Phantom's Touch' is a great title. It makes you think of an unseen, ghostly hand touching you. 'The Darkest Hour' implies that something truly terrifying happens during the darkest part of the night or a difficult time. 'The Hollow Eyes' is also quite effective as it makes you wonder what kind of creature has those hollow eyes.
Midnight at the Cemetery Gates. Just the mention of midnight, which is often associated with the unknown and danger, and cemetery gates which are the entrance to a place full of the dead, makes it a cool and scary title.
There are many more. 'The Rainbow Bridge to Asgard' - Asgard is from Norse mythology, and a rainbow bridge leading to it is very much a fantasy concept. 'The Golem's Awakening' - a golem is a powerful and often mysterious creature in fantasy, and its awakening means there will be big changes and events. 'The Mermaid's Sunken Palace' - it combines the beauty and mystery of mermaids with the idea of a sunken and perhaps long - lost palace.
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.
