The 'experience' of an experience

Often, we say that we undergo a unique experience. One that may change the course of our lives, shake our beliefs, rattle our conscience and flare a whole host of indescribable emotions in us.

Yet, this always seems to be observed retrospectively.

When it occurs, what is the experience truly about? You know that it is going to be unique, shivers shall pass down your spine as you walk away from it. Yet the moment is oft inexpressible in the present. What truly is the 'experience' of the experience itself?

We change our behaviour, our thoughts on incidence.
We change irreversibly.

On noting the reason, we realize it was due to us having experienced the moment. Now a memory of it remains. It is presumably difficult to feel the exact same emotions as you had at the incidence, yet they've left an adequately deep impact which prevents you from retracing your steps.

There may have been a surge of chemical reactions in your brain which seemed to have created a complex understanding of the situation and which in parallel, redefined your script forever.
Coincidently, this is also probably the reason why you felt the moment, but can't truly remember it.

Its there. Staring at you. In front of your face.
You understand what it says, but YOU.... CAN'T... SEE.... IT.

Its searching for these moments in our everyday lives which can send our lives into a focussed Brownian Motion ( pardon my Physics, its a little insane ). When in each day, through glaring mistakes, through daring acts, you grow phenomenally.

You know you grow.
