I'm not sure how i to explain, because it's not easy for me this area of study. There is a part of us, the mental body, of which the subconscious is part of. I believe that they are transmited through the genetic code and when in the womb (mother->baby). It's like when animals react to predators/danger like they know it's dangerous. Like a fish, if you try to catch it swims away even though it wasnt "teached". Is there an explanation for this? thanks!
