It's like a smell!!

When a sound brings that all familiar feeling, a nostalgia sometimes, often it's like a smell! One which reminds you of a specific moment in time that you experienced, or in some cases, believe you experienced (see de ja vu).
But a sound is all so very different and complex. Perhaps like a vision, it can make you have goose pumps with an excitement or anticipation of wonderment!!
Perhaps even more complex than that, as a sound, when mixed with a vision can bring about many feelings at once! One of the most powerful feeling I have ever experienced, is an emotive sound, with that of an epic image or series of images, that connects to you, personally. For whatever reason, morally, emotionally, physically, that combination is insanely powerful. Almost explosive!
Aside from this, sound on its own, with a somber thought, hard day, worst received text, or argument that makes you over think can also feel at that time catastrophic!
As we feed from it, we perhaps want or need to shed those tears, after all it's natural.
And we have the almost opposite, when sound is made to encourage a happy sensation, a jovial sound, when mixed with alchohol, but no where near as powerful as a sound when sober!!! Worth thinking about. Perhaps our natural inclination is to feel, or want to feel low?!
