Why we fear?

Fear it is a natural mechanism of the body to protect itself. But I am not told that mechanism that why fears that seem to be able to feel from within consciousness. Or not only the fear but also the emotions, whether the body evolved to represent the basic information of the sense or simplicity of the body that creates it and the sense of learning to survive deep inside and is the source of information for the Evolution
. 
Essentially I am quite confused about this problem.

I think it’s best to keep both ideas on the table. It may be we find a way to understand nature that allows both to be correct.

For me, fear has a lot of coherence. As a pattern of coherence, it matches up with other identical patterns across spacetime, it connects up with lots of identical patterns, and that’s why it’s such a strong feeling... lots of coherence. I can’t really hazard a guess why... sometimes it seems like I’m ‘searching’ for a matching pattern when we don’t understand something... so we spread out in spacetime looking for a match, and it’s that wide searching for a pattern, which causes the mass of coherence. But I’m not very sure about this.

However, non-classical coherence (adding up) of matching patterns which transcend spacetime is the best way I’ve found to think about it, whilst trying to explain our observations, and the anomolous stuff we discuss on here.
