Final answer:
Thomas's phrase 'face to face with one's own ghost' is a metaphor for confronting one's past actions and regrets. It signifies personal reflection rather than a literal ghost encounter or a religious experience.
Step-by-step explanation:
When Thomas refers to being "face to face with one's own ghost," he is speaking metaphorically about encountering one's past actions, behaviors, and possibly, regrets. This phrase suggests a moment of self-reflection where a person comes to terms with the impacts of their previous decisions, akin to facing the 'ghost' or the lingering presence of those choices. It can be seen as a confrontation with one's conscience, rather than an encounter with the supernatural or a mystical experience.
The context provided also touches upon religious experiences, where individuals feel a connection to something beyond the material world. While Thomas's statement could metaphorically relate to this concept, it is more likely focused on personal introspection and accountability. This aligns with the broader experience many individuals have of sensing a deeper reality or truth that influences their moral and existential perspectives.
