Anectine and great memory

When I was seven years old i had my tonsils removed, now 24 years old. They used Anectine on me, when I had awakened the doctor was telling me not to worry. I couldn't move, I couldn't respond, I couldn't give them a sign that I heard them, and I was seven years old very very scared. I remember coming out of my body, hovering to be exact. My father had bought me a new Wilson basketball, my first basketball ever. The next thing I remembered is me waking up and asking where my family was and my new basketball. Everyone was shocked about me knowing about the basketball, the doctor had explained that I had "heard it". Me being a person with great memory, I explained to everyone that the label of the basketball was "Wilson". That is when the doctor had explained the whole theory about "coding".

I am not really sure what had happened that day 17 years ago, but for some reason I think it has happend to someone else or someone knows exactly what that "coding" was.
