Second Amendment? What Second Amendment?
I did that to a guy years ago in a deep hypnotic trance as an experiment. Using the subconscious suggestion that the number 6 would not exist to him until I snapped my fingers two times. This was done as a post hypnotic suggestion.
Several hours later I asked him to count to ten. He skipped the number 6. I then asked him what 3 + 3 was and he could not answer it. Freaked his wife out. I then snapped my fingers twice and it was back.
The emotional subconsciousness is very programmable when a person is in a deep trance. The Jason Bourne type events are possible.
