Take from the clip what you will. I find the clip very validating and relevant; especially as to those individuals whose DP/DR began with substance use and the embedding of a strange theme. For myself, ocd preceeded dp/dr, which I had for 3 years 07 to 2010, and has still proceeded post dp/dr. Look for more works by this man if you think an obsessive element plays a significant or even partial role in your dp/dr.
