I am just an imagination

I am just an imagination,
A respite from the present's realm,
Far away from this day's heartaches,
I seek shelter in tomorrow's shattered dreams.

Wandering through time and space
I am on a tricksy tightrope walk,
Imagination morphing into memory
One step in the future, one in the past.

And the big wheel keeps on turning
Through scarlet autumns and frozen winters,
But on the fringes of spring and summer
Is where my hopeful heart lingers.
