Sure. Some fake university names could be 'Sunnydale University', 'Mysticville Institute' or 'Fantasia College'.
Some names for fake horror novels could be 'The Unreal Serial Killer of the Small Town'. It gives the chills of a horror story but is not based on real horror. 'The Bogus Poltergeist in the Attic' is another one. And 'The Fictional Demon in the Graveyard' can also be a name. These names are designed to attract horror fans but with a twist of being not - real horror stories.
You could use 'Moonbeam University'. It has a kind of otherworldly and dreamy feel. Another one is 'Glimmer Grove College', which makes you think of a beautiful, maybe slightly enchanted place.
Mystic Grove Academy. 'Mystic' implies mystery and magic, and 'Grove' gives the idea of a natural, perhaps enchanted setting, perfect for a story about young wizards or witches.
Vladimir. It has a dark and mysterious sound, often associated with vampires in gothic literature. Another could be Isabella, a name that can be both elegant and a bit spooky. And then there's Damien, which gives off a menacing vibe.
Eternal Nightmare. This name implies that the horror within the story is never - ending, like a nightmare that just won't stop.
Sure. 'The Ghostly Gaze' or 'Deadly Whispers'.
The 'Glitter Lung', which is caused by inhaling magical glitter dust in a fantasy world. Another one could be 'Rainbow Rot', where the body parts start to show rainbow - colored patches as a result of a strange magical spell gone wrong. And 'Frostbite Fever', which occurs when a character is exposed to extreme cold magic and then develops a high fever with icy symptoms.
Smith. It's a very common last name and can be used for an ordinary character in the story.
Bellatrix. This name has been made famous by the 'Harry Potter' series as the name of a very evil witch. It has a certain elegance combined with a sense of danger and evil, which can be very appealing for a story's antagonist.
