You do realize that we are all human correct? Therefore, I'm curious as to what you meant with the title of this thread. I digress, however.
Also, I'm certain several individuals on this site have similar abilities, myself included. I can sense the presence of entities and on occasion have also seen them. The ability runs in my family on both my mother and father's sides.
Also, I would be careful with this ghost hunting of yours as some entities can be quite nasty when provoked or bothered. Therefore, be cautious in your excursions.
To be honest I didn't know that a ghost could actually be "destroyed." From all that I've read and learned they can simply be banished from the area in which they reside or helped to fully cross over.
Blessed Be and With Respect,
