I've said many times, spiritual senses such as empathy, clairvoyancy, clairaudiency, etc are all just as natural as our physical senses, but they go unnoticed by most. They are merely the spiritual counterparts.
Just as our sense of touch is never 100% used and mostly unnoticed (how often do you feel the ground under your feet? Your clothes on your skin?), so too are the spiritual senses regularly ignored. When someone begins to pay attention to these senses (held onto since they were children or regained through awareness brought on by meditation and spiritual studies) these senses reappear and grow stronger as they continue to be deamed important to the individual.
