I am not sure of the scientific explanation but, there has been many times when a pregnant mother gets scared to the point of something it causes what they call a mark on the baby. I understand it well with the food parts and seen it many times. The only way it makes sense in the feeling part is for the baby to be sensitive enough to pick up on their mothers emotions. maybe the baby can pick up on the vibes of whatever scared the mother and it feels the same as the mother did? I remember as a child, the grownups claiming they can smell a snake close by and to be on the lookout. Maybe there is a smell that I never picked up on? With my chronic sinus problems all my life, I missed out on alot of the smells.
