To write someone stuttering, you could describe their facial expressions and body language that show their frustration or nervousness. Also, vary the speed and rhythm of their speech. For example, 'He stam...stammered, his face turning red as he tried to say, 'I...I can't do it.'
Start with a unique and lighthearted setting for the ghost. Maybe have it in a place like a funfair or a comedy club. Also, give the ghost a comical personality or quirks.
First, build a creepy atmosphere. Use vivid descriptions of the setting and sounds. Then, create mysterious characters with hidden pasts. And don't forget a twist at the end!
You need to build a creepy atmosphere first. Set the scene, maybe an old abandoned house or a dark forest. Make the readers feel the chill from the start.
