In the book "Voyager" by Diana Gabaldon, a character reflects on extraordinary experiences where some individuals can leave their physical bodies and travel far away. She notes that these out-of-body experiences are sometimes witnessed by others who can attest to the individual's actual presence in bed, creating a fascinating dichotomy between the physical and spiritual realms.

Additionally, she mentions stigmata, which only appear in certain people, emphasizing that not everyone experiences these phenomena. The character's contemplative observation highlights the unique nature of such occurrences and the intriguing evidence that supports them, suggesting a deeper connection between the mind and body.
