My amazing, thing?

Its like you have this amazing thing, 
only you know about, 
only you can feel, 
only you can think about.
You can recall every little detail of that amazing something. 
You keep imagining it, thinking of it.
And then suddenly, you don't remember it anymore. 
You know it was amazing, but you don't know how was it like.
You don't remember.
And you start looking around for people to assure you that you were not imagining it all along. 
That it existed. This amazing thing.
But the thing is, only you knew about it.
      The amazing thing, was only, for you.
And then a stupid little thing happens, like a smile, a glance.
And it all comes back flooding at you.
And you feel grateful, that you can remember your amazing thing again. 
Because you felt like you lost it, forever.
Except that, it might not be an amazing thing. 
It can always be, a person, too.
