Buried leaves

I buried heaps of leaves
Under my cosy bed;
Years later, they turned
A uniform brown,
Those, which were once
Green, yellow and red.

To have a glance
I dug them out and reread;
Left out for long, they appeared
Indecipherable, blurred
Lost their outstanding stance.

Once upon a time
They were also words;
I felt them alive within, afresh.
