What keeps you awake at night?

What keeps you awake at night?
An old dream which never came true,
A memory which is hard to forget,
Or a song which was never sung perhaps

What keeps you awake at night?
Hoping for a never ending journey
On a lane you walk every night,
Wandering aimlessly by the riddled maps

What keeps you awake at night?
A purple bike,a hand-made card and an old chocolate box 
A companion, an old friend and an alter-ego such a delight
A path never met, a hand never held, a forbidden fruit never bitten

What keeps you awake at night?
The river that lured or the fate that consumed
The death of a confidant or the unfinished story of the living,
An empty hug, a restless soul and a craving heart?
