Hell, no! Believing that "possession" CAN happen to you makes you easy prey for being mentally manipulated. People who think they are going to die actually die sooner. People in line at the gas chambers of Nazi Germany simply collapsed and gave up the ghost. They died of "fear of oncoming death". Answer: believe that you are IMMORTAL and EMOTIONALLY INDESTRUCTABLE. There is NEVER any point in believing that you can be: destroyed, hypnotized, brainwashed. With a few high-tech tricks, you can convince somone that they are "possessed". They are prisoners because they believe in possession. I simply DON'T, because someone who thinks they CAN be "possessed" WILL be in today's subliminally/media-controlled society!
