Flashback

Sometimes I have flashbacks of the days I regret
sometimes my dreams are nightmares,
my mind does nothing but fret.
These thoughts they give me scares,
they frighten me to death.
These dreams they are so vivid.
My past is giving me a heart attack.
But what frightens me?
The past is done and gone
I've moved on,
but in the back of my mind
I wonder all the time,
what if it happens again?
What if I screw up once more?
The flashbacks come,
the nightmares rise,
oh how I hate remembering
my almost demise.
