I couldn't see him, but I knew he was nearby. His presence was made known by the gentle sounds he produced, such as his soft snoring and humming, which created a sense of comfort and familiarity. It was as if he was peacefully resting or perhaps lost in his own world, like a tiny airplane wandering aimlessly among the clouds.
This quote captures a quiet, intimate moment where the speaker is aware of someone through their subtle noises rather than sight. The imagery of the humming and snoring as a little airplane in the clouds evokes a feeling of gentle serenity and a touch of whimsy, emphasizing the peaceful, almost dreamlike atmosphere of the scene.
