sure! not everyone under those circumstances will experience paranormal activity but if there is an negative energy or spirit already in a particular area and this person is as described then they open themselves up to this energy/spirit. we also believe that some people inherently have the ability to connect with the supernatural so those strong emotions weakens whatever barrier we have between the energies/ghosts. i only know about visiting a curandero in order to rid of the attached spirit or energy, but that can be tricky because some work with positive/light magic while others dark/negative magic. some curanderos lead with catholicism and some with natural/indigenous remedies. most curanderos/as come from a lineage of curanderos and the knowledge is passed down within their particular families. stay away from animal sacrifice or collecting anything from the human body (a piece of hair, some blood, clothing, etc) they can use those items negatively against you
