I don't believe you remember anything in the womb or as you are born. HOWEVER....those memories are stored in your brain. Here's my theory. You know how people who have come back from being dead all say that they see a bright light and they want to go into the bright light? I believe that as you die, your last thought is your first thought, which was being born...going from darkness into the light. Pretty smart, eh??? :)
Well they don't all say that, some report no experience at all, others tell of simply arriving in a heavenly (or a hellish) place.
But the sight that the infant has while passing through the birth canal would not match up with the "tunnel" story. Its eyes would be pressed against the side of the birth canal and it could see nothing at all until it had come out as far as its eyes, then as far as it knows it is completely in the light.
