To compare your state of conscience to that of a zombie is a fairly accurate decription for DP in my opinion. Having DP feels like a state between life and death. Believe it or not, voodoo priests in Haiti have actually created zombies by giving unsuspecting victims a potion consisting of a neurotoxin(derived from a puffer fish). The victims were then burried in an actual coffin only to be exhumed later and then kept as slaves, and they described being in a dream like state, unable to move their limbs, but still being able to hear everything in their surroundings; incuding their own funeral procession!!! Perhaps something in our body is creating neurotoxins, evoking this perpetual dream-like state of mind.
