Sure. There are stories where electric guitars for kids are part of the plot. These guitars can represent a character's passion for music. It could be a story where a child discovers an old electric guitar in the attic and starts a journey to learn how to play it, facing challenges and making friends along the way.
They can be a symbol of a child's dream. For instance, in a story, a kid dreams of becoming a rock star and the electric guitar is the key to that dream.
I'm not sure specifically about a 'Josh Williams Guitars horror story'. It could be that there was some sort of spooky encounter in a guitar shop owned by Josh Williams. Maybe there were rumors of guitars coming to life at night, or strange noises coming from the guitar cases. But without more context, it's hard to tell the exact story.
One element could be a haunted guitar. For instance, it might have belonged to a deceased musician, and their spirit somehow lingers in the guitar. Another element could be the guitar making strange noises or movements on its own, like the strings moving without being touched.
Dean's driving can be a way to show his restlessness. Sometimes he just gets in the car and drives without a clear destination, which could be a sign that he's trying to run away from his inner demons or difficult situations. He might drive for hours, lost in his thoughts, which gives an insight into his complex and often troubled mind.
Dean is likely a character who has some sort of relationship with Harry within the context of the fanfiction. He could be a classmate or a fellow wizard. He might be someone who has certain qualities or achievements that make Harry jealous.
