Yes, I strongly believe that there is a connection. Although it doesn't necessarily mean that this has anything to do with reincarnation. My personal view is that in certain aspects, they are part of a cycle a soul goes through. Let's say a particular soul is "given a chance in the mortal world", from the spirit world it passes through a certain tunnel, becomes part of the human process of birth, then becomes part of the mortal world through birth. The birth canal is that part of the cycle wherein that particular soul who has became a mortal exits from its water-world (the womb) into the outside world where it undergoes the human part of its evolution. Then at the time of the death of its mortal body, the evolved soul goes back to the spiritual world through the same tunnel where it first went through. Basically and figuratively, if a baby can only remember the experience it had when it passed a birth canal (dark tunnel and blinding intense light at the end of the tunnel), that baby will surely attest that the experience is very much similar to that experience it had when it was once a soul, and again when it becomes a soul again.
