Well, it could be about a near - miss situation. For example, a character was almost in a car accident but at the last moment, it didn't happen. Maybe they saw a car speeding towards them while crossing the street, but then the car swerved away just in time.
Sure. There was once a person who received an offer to work in a very far - away place. It seemed like a great opportunity at first. But then, some family issues came up and they couldn't take the job. Later, they found out that the company they were supposed to work for had some financial problems and had to lay off a lot of employees. So it was the best that this job transfer didn't happen.
One story could be about a person who was wrongly accused of a crime. They were on the verge of being convicted when suddenly, new evidence emerged that completely exonerated them. It was like 'this is not happening' in the best way possible as their life was saved from being ruined by a false conviction.
Sure. There was a story of a lost dog that had been missing for months. The owner had almost given up hope. One day, the dog just showed up at their doorstep, looking healthy and happy. It was like 'this is not happening' but in the most wonderful way.
