The Shadow

I saw a dark shadow with a wicked smile,

She disappeared from my room just in a little while.

Her ghastly appearance still wanders all around my mind,

She may be a spirit whom I could ever find!

I always wondered what she was about to say,

Or she wanted to kill me or guide me to a way.

That shadow is still an unsolved mystery,

I wish to reveal its truth but I feel it's like an old history...
