Paranormal Investigators intermittently possessed?

I was recently invited to a local paranormal group's meeting. They dicussed ethics in the workplace, and were complaining about certain members of the crew who would bicker amongst themselves and "swear incessantly" while setting up cameras in someone's house.

I asked the Executive Director later by email, whether he had ever considered that these bickering, swearing camerapersons might be being intermittently possessed. If you were a ghost and you didn't want to be detected by these cameras, wouldn't the best place to hide be in the body of a camera person, who stays BEHIND the camera?

They had invited me to nail down a possible date for them to come over and film me doing an energy healing/spirit depossession session. They offered to use their thermal imaging cameras to try and catch something coming out of the body of my client.

I think my do-it-yourself space claiming kit might be a good thing for all paranormal investigators to have.

After all, isn't it usually "Sensitive" people who go into this business anyway? They tend to be more susceptible to spirit possession than others.
