Shadow creatures are often described as dark, amorphous figures that appear in low-light conditions. They are typically associated with feelings of fear or unease, as they seem to move quickly and unpredictably. Many people report seeing these figures out of the corner of their eye, leading to speculation about their nature and origin. In folklore and popular culture, shadow creatures are sometimes linked to ghosts or spirits, representing the unknown aspects of the human experience. While some believe they are manifestations of anxiety or stress, others view them as supernatural entities. Scientific explanations often attribute sightings to optical illusions or sleep-related phenomena.
