This is another clip that was featured in Science of the Soul that I watched a few months ago on History International. Incredibly fascinating, another reason I was able to watch this for 2 hours at 2am in the morning.
What is interesting, is that I think many if not all of us, have these experiences in youth but later 'forget' or don't recall maybe as well as the person next to us. I had similar events around the age of 4, including the beginning of a 'nightmare' that followed me into adulthood as a reoccurring, occasional dream. For 2 days after I first had this nightmare at 4, I felt as if I were walking through fog everywhere, in slow motion - nothing felt 'right' even though everything looked familiar. That soon passed but I still recall those feelings afterwards.
Namaste'
