Given its profound history and the intense human emotion that has saturated its very fabric, it is perhaps unsurprising that Gracanica is also the subject of numerous accounts of spectral activity. For generations, visitors and, more significantly, the resident monastic community have reported inexplicable phenomena, leading to the monastery gaining a quiet reputation for monastic apparitions.

The most common reports involve the subtle yet unmistakable presence of unseen entities. Cold spots, sudden gusts of wind in enclosed spaces, faint whispers that seem to emanate from empty corridors, and the fleeting sensation of being watched are frequently cited. More strikingly, there are accounts of full-bodied apparitions, often described as robed figures gliding silently through the cloisters or kneeling in prayer within the main church, only to vanish when approached. These figures are typically perceived as benevolent or melancholic, believed to be the spirits of former monks and nuns, forever bound to the holy ground where they dedicated their lives. Some accounts speak of phantom liturgical chants echoing from the church after hours, or the distinct scent of old incense when none is being burned. These occurrences are not sensationalised tales for tourists but are often recounted with quiet reverence by those who have witnessed them, reinforcing the belief that Gracanica is a place where the spiritual realm is exceptionally close.
