These sightings are often brief, lasting only moments, and frequently occur during twilight hours. The prevalence of these visual disturbances contributes significantly to the persistent narrative of unexplained phenomena in Mynydd-bach.

Animal reactions are another frequently cited indicator of paranormal activity in Mynydd-bach, with domestic animals like dogs reportedly exhibiting agitated or fearful behavior in areas where humans subsequently experience unusual events.
