Clairalience Psychic Smell is the ability to perceive scent without a physical source. People with clairalience may smell smoke, metal, mold, perfume, gas, or decay even when nothing in the environment explains it. These scents appear suddenly, disappear quickly, and are not imagination or memory recall. Clairalience functions as a form of sensory-based intuition, where the nervous system detects emotional pressure, unresolved containment, or energetic instability before the conscious mind can interpret it.
