A valuable painting goes missing from an art gallery. The detective finds a small piece of fabric on the frame that matches the clothes of one of the janitors. Upon further investigation, it turns out the janitor was blackmailed into stealing the painting by a rival art dealer.

A character vs. technology conflict could be interesting. For instance, a writer who has always written with pen and paper suddenly has to switch to a new high - tech writing device for a project. The device keeps malfunctioning and has a complex interface. The writer, who is used to the simplicity of pen and paper, is frustrated and has to struggle with the technology to meet the project deadline.

Sure. 'Haunting' is a good one. It can be used to describe a memory or a place that keeps coming back in a disturbing way. For example, a haunted mansion where strange things happen. 'Sinister' is also great. It implies evil or malevolence, like a sinister plot being hatched by the villain. Another word is 'uncanny', which means strange or mysterious in an unsettling way, like an uncanny resemblance between two people that has no obvious explanation.

A plot about a person who wakes up one day to find that they can hear other people's thoughts. At first, it seems like a cool ability, but soon they realize it's a burden as they hear things they don't want to. This can explore themes of privacy, empathy, and the human mind.

A story about a detective who is trying to solve a series of mysterious disappearances in a big city. There are no obvious clues, and the victims seem to have no connection at first.

A Christmas story could be about a family that adopts a stray dog right before Christmas. The dog seems to have a mysterious ability to find lost things. As they prepare for Christmas, they realize that the star for their Christmas tree is missing. The dog leads them to an unexpected place where they not only find the star but also discover a hidden box filled with old family Christmas memories. This discovery brings the family closer together.

One idea could be a story about a woman who moves into a new apartment. Every night, she hears strange scratching noises coming from the walls. When she asks the neighbors, they all deny hearing anything. As she investigates, she discovers a hidden room behind the wall in her bedroom. In the room, she finds old photos of a girl who looks exactly like her but from a different era.

One idea is to write about a character who is a dream - walker. They can enter other people's dreams and change them. But one day, they enter a nightmare that they can't escape from. Another interesting concept for short flash fiction is a world where music has physical forms. For example, a sad song might look like a grey cloud hovering over the singer. A character could be on a journey to collect all the beautiful music - forms in the world. Also, you could write about a society where people are born with a number on their forehead that represents their lifespan. A person who discovers their number is much shorter than they thought has to decide how to live their remaining days.
