Sure, a novel can switch person of view. It's a common technique used by authors to add depth and variety to the storytelling.
First off, focus on the narrator's thoughts and feelings. Let the reader really get into their head. Also, be consistent with the narrator's voice and personality throughout. It helps make the story more immersive. Another key point is to show how the narrator interacts with the world around them and how that affects their perspective.
To switch to first person, focus on the character's internal dialogue and emotions. Make the language personal and immediate. Also, think about how they perceive the world around them and describe it from that unique perspective. It takes practice to make it feel natural.
One advantage is the immediacy. It makes the reader feel closer to the protagonist's thoughts and emotions. For example, in 'The Catcher in the Rye', Holden's first - person narration lets us directly experience his angst and alienation.
An omniscient first - person view novel often gives the reader a sense of being all - knowing through the narrator. The narrator can provide insights into other characters' thoughts and feelings while still maintaining a first - person perspective. For example, in some classic novels, the first - person narrator might share what they observe about a character's hidden motives or unspoken desires.
