Yes, it would be interesting to hear if he remembers anything those 4 days.  Hopefully he actually got to go out and explore and didn't just lay there bored out of his skull!

Once when I was knocked out for dental surgery I thought I was awake and aware the entire time.  I could see and hear everything that was done and said.  I was utterly bored that whole time.  But if I had known my state at the time I would have willed myself elsewhere and had some fun!

Another time when I had major surgery to remove a tumor from my lung I thought I was awake, having woke up right after the surgery.  It turned out I was still asleep from the anesthesia.  But all I did was lay there "in" my body, again bored out of my mind.  I remember hearing the nurses talking, then could hear my parents chatting on about trying to remember how to set up their camping tent for my 5-year-old nephew who had asked to camp out in the backyard that night.   (It was indeed a tricky tent).  I was so mad that here I was waking up from surgery and my parents were just casually talking about the tent!  Well, when I actually finally did wake up, I told my parents the correct way to set up the tent as they walked into my room.  They were shocked that I had known what they were talking about, but I told them they obviously must have been standing in the doorway or something.  But they had not been and were not even close to my room.  They were literally down the hall on the other side of the hospital and there was no way I could have merely physically heard them talking.  They verified exactly word for word what I heard them say.  So, I wonder why I was able to hear their conversation yet it was from the vantage point of my physical body.  It seems my visual sense was focused in my physical location and my hearing sense was focused in my parents' physical location. 

It's so good to see you both here, Vicky and Ricardo.  Vicky, I agree, that's an amazing experience!  Thank you for sharing, and I will certainly keep the possibility of this kind of freedom in mind in case I am ever in a similar situation!

love, blink
