Never-ending nightmares

I look at you and call your name
As i watch you walk away
I chase after you
Running faster and faster
Trying to caught up to you
Only to be sent back to the moment i saw you

I tell you wait up but you keep going forward
Just as time reverted itself
Every time getting closer to you
To find that i am nothing to you
I am right in front of your face but yet you go though me
Like i am a shadow

Do i even exist?
Do you even care?
These questions go though my head
As i live though my greatest fear.
