This quote beautifully captures a sensation that transcends the mundane experiences of life—the feeling of an unseen presence that is nonetheless comforting and reassuring. It evokes a mystical or supernatural atmosphere, where the narrator acknowledges an unshakeable sense of not being alone. What's compelling here is that this presence is not frightening or ominous; rather, it's described as "something good and pure," highlighting an innate positivity and warmth that the narrator senses.

The phrase "something in the air" suggests an intangible essence, an energy or spirit that is palpable not through sight but through feeling. This resonates deeply with many people's experiences of moments where they have felt comforted by something beyond rational explanation, an ethereal force or energy that offers hope, connection, and reassurance.

Moreover, the lasting nature of this "beautiful energy"—something the narrator says has been with them ever since—emphasizes its profound impact. It hints at the possibility that such energies or presences could act as guides or guardians, providing strength and serenity through challenges or uncertainty.

Taken within the context of "Paranormal Intruder" by Caroline Mitchell, this quote may reflect themes of the paranormal as not solely defined by fear but also by moments of grace and protection. It invites readers to reconsider the paranormal not only as an external threat but as a source of enduring comfort.

Ultimately, this passage speaks to human yearning for connection, reassurance, and the hope that amidst the unknown, there exists a benevolent force watching over us.
