It might be possible. However, some places may have restrictions on fanfic due to copyright issues. It's best to check the rules of where you're submitting.
One could be about a little girl who discovers a magical box of candy samples. Each candy she tries takes her on a different adventure, like flying through a land made of marshmallows with a candy cane as her wand.
Recall bias can be an issue. When people are asked to share their life stories, they may not remember events accurately. Memories can be distorted over time, and this can affect the reliability of the samples. For example, someone might overemphasize positive events and downplay negative ones.
Vision is also crucial. Take Bill Gates for example. He had the vision to see the potential of personal computers and founded Microsoft. His foresight allowed him to create software that became an essential part of the digital world.
One sample is through physical description. For example, in 'Pride and Prejudice', Jane Austen describes Mr. Darcy as tall, handsome, and having a noble air. This gives the reader an initial image. Another way is by showing a character's actions. In 'The Great Gatsby', Gatsby's elaborate parties show his longing for something, perhaps acceptance or love. Also, a character can be defined by their dialogue. In 'To Kill a Mockingbird', Atticus Finch's wise and calm words in court reveal his moral character.
Candy samples can be incorporated by making them the rewards in the story. Like the characters in the bedtime story are on a journey, and whenever they complete a task, they get a candy sample. You can describe how delicious each sample is to make it more interesting for kids. Also, you can have the characters use the candy samples to solve problems. For instance, a mint - flavored candy sample can be used to cool down a hot path they need to cross in the story.
Yes, I once got a sample of a frozen meal. It was thawed out but still cold in the middle. It tasted really bland and not at all like what the description said. It was a big disappointment.
