I am coming to believe most of what Lapis said above. Since we exist at more than one level of being this state that we are most conscious of is akin to the other states in which we also exist. I wonder if our other soul existences dream of us in this plane.
Some very universal symbology probably exist but because of cultural/locational and other differences broad typing is not completely viable. There may exist ancient symbologies or unspoken languages that imprint within us all but they would come from higher realms and will have been known from antiquity.
My personal experiences show that a language that does not exist in words is written in my heart from time to time. I just know it and can express the action that it leaves me with but my verbal language does not hhave the words to express it. The only thing I can do is live by the positive actions that proceed as trying to explain proves fruitless much better to just let the fruit produce and it may inspire others in the process.
