The quote reflects the complexity of human consciousness and the varying levels of self-awareness people experience. It suggests that many individuals often go through life on autopilot, unable to fully grasp their actions or decisions. This journey through life can lead to moments of disconnect between one's intentions and their behaviors, highlighting the intricate nature of self-perception.

In Sebastian Faulks' book "Engleby," this theme is particularly resonant, as the protagonist struggles with understanding himself and the world around him. The acknowledgment that many people, including the narrator, operate on different planes of awareness emphasizes the importance of introspection and the challenges that come with gaining clarity about one's thoughts and motivations.
