The Watcher in the Shadows

There's someone following you
You can't run away
You can't escape
There's no place to run
You are trapped
Around every corner he's there
He's watching you
He knows everything about you
Your strengths; your weaknesses
He's waiting for the exact moment
He is patient; he can wait
He'll always wait for you
You fill his mind
You poison his thoughts
He always looks for you
He'll never give you up
He wants you for himself
He can't stand sharing you
He wants you for himself
You poison his thoughts
He knows everything about you
You can't run away
You can't escape
There's no place to run
He'll always be there
He'll forever haunt you
Pretend you don't see him
Never say hello
He is watching
