I saw this site quite accidentally and exited to read this article. I noticed in your profile that you are still an undergraduate student. The language and presentation shows maturity of a senior research scholar. I wish to appreciate you for your natural brilliance and erudition.
I am not a man of science. My interests are in yoga and mysticism. I don’t know whether you are interested in it or not -probably not, because it needs an age and experience to enter in these kind of thoughts.
As per our yoga tradition which is an integral part of Eastern mysticism we have four levels of mental existence. Jagrat, svapna,sushubti and durya. I may compare them with the modern psychological terms conscious, subconscious, unconscious and collective unconscious. Well, actually there is sharp difference between these eastern concepts and western terms. Western psychology assumes these states as structures and we think them as functional modes.
According to yoga tradition we are existing in all that four levels at the same time. But one is screening the other. We can say, durya is screened by sushubti and sushubti by svapna. Jagrat covers everything as an iron curtain and it presents itself as the only self we have. Jagrat is made up of logical thought, signs and symbols, images and its endless associations. Language is the presentable form of jagrat.
Jagrat is a creation of culture. According to yoga sastra human beings created their jagrat and continuously making it stronger. Every living thing has day to day life, so it must have a jagrat. But in the case of lower level beings their jagrat is weak, so their other inner selves are stronger. Animals have more mundane life than insects. So their jagrat is stronger than them. So naturally their svapna and sushubti are weaker.
This is the explanation of yoga sastra for your question. When we began to build our jagrat or conscience for our survival we lost our connection with the durya, the collective unconscious. We lost our intuitional powers as well.
This may not seem as science, but a religious belief, but yoga says one can suspend his jagrat slowly by practice and attain the inner existence gradually. He can reach and be in durya state, merged in collective unconscious. On that stage he may predict earthquake like an animal or insect. As per our tradition the highest state for a man.
Not for this discussion but for general understanding
