When someone is trophying, that person is turning their spirit unholy.

In trying to possess what belongs to the Lord, that person is sinning and breaking spiritual law, thus unholy in spirit.  

Automatically that puts the perpetrator, trophying in sin, on a different spiritual plane than the victim.  

The trophying sinner will, in sins, be negative and on the path of the unholy and damned.

Thus, the person actually possessed is the trophying perpetrator by sin and Satan.
