Fate and Blackholes

In a world where communication was nonexistent in verbal tongue what would it be like? It's hard to imagine since the verbal is what we have grown in this world expressing. How would a thought pass through your mind? Visually? Chemically?
The first thing that comes to my mind is instinct; the instinct to fight or run, the instinct to reproduce. You can look at an animal, their instincts to run when in danger, but they too have some sort of way to communicate as well. How would it work, would there be some sort of switch that the brain would somehow flip on or off according to the situation? Would you just picture yourself doing something instead of having that verbal thought? Be presented with something wanting to attack you and picture yourself being eaten, or picture yourself running away or standing on its defeated corpse?
And while I am on this thought, how exactly does instinct work. I know it's some sort of thing that has been passed through our animal sides, but what is it exactly? Could it be possible that instinct is a learned condition? Theoretically thinking if you were to raise a child with rabbits and not have any connection to the child in the means of acknowledging that the child is human their instincts would be different than that of a human. Same goes for a child that was raised with anything higher in the food chain. That child would grow up living as if it were that creature and have the same instincts. Now what if a child were to be raised in a situation where there were no instinct like environment presented to the child? How would that child grow up, would they not know what danger is? Would they not care or embrace it? How would the fight or flight instinct work, or the need to spread your seed and legacy? Would that child still get that crawling feeling on the back of the neck when in danger, or that sinking feeling when they know that something is amiss? It's all psychological, not so much in your genes.
On the topic of the sinking feeling, the crawlies on the neck, and the chills down the spine when things are going to go wrong. The sort of "Intuition", this ability to scry forward in time and feel the upcoming "fate"? I see fate as some sort of black hole, the closer you get to it the stronger the force is telling you something is near... unless you are one of those people that don't really care about those feelings and go on with it anyway. For those who are lost, in theory- the closer to a black hole you get the stronger the gravitational pull becomes. The stronger the pull of gravity the faster you travel toward the event horizon, the faster you travel the slower time travels. Eventually you reach the event horizon, that center point, the paradox that decides your fate... will you be warped to some other dimension, or will you be ripped to shreds in the process? No one can know because no one has tried to test the event horizon and no one should tempt fate.
hmm... it's an interesting though.. keeps me up sometimes wondering... I hope to sleep now since I wrote it down.
