Introduction To Sensing? Options

Hi. My girlfriend who is naturally sensitive to the presence of apparitions and ghosts has as of yet not been able to unlock her full potential or rather abilities that have been bestowed on her. She craves proper accurate guiding that of which I cannot fully provide for her. Her senses are present when she is near a place where there is likely to find such an apparition like nursing homes or burnt down houses, though not limited to these specific areas. Gradually along the course of her life, encountering moments where she would sense one have decreased substantially. She wishes to attain this ability once more and amplify it to her full extent and potential. Her only obstacles are a vague understanding of these entities and fear of them in result of that. Anyone have any advice as to how she can go about introducing herself to it again and increasing her own understanding and perspective on the subject. Thank you.

Any information or advice is greatly appreciated. Thankss
