what was that?

Did I just imagine that I was sad? 
When was that dream that I had?
I know it's normal and life has us move on
But I have moments of weakness where I just don't feel strong
I know it's not wrong
We have to be open to life and it's change
We need to remember what we learn as we age
I still can't help but to think of the past
And to wonder if I could have made those moments last
You really do need to take it all in
And accept everything as it is, the change is within
Every moment. Even how hard it may be.
Perhaps I should remain silent. 
Walk it out.
