Why can't I dream of you?

I think of you every minute of every day,
But when I lay my head on my pillow and drift away,
You are never there, I don't like it this way!

While I sleep my head maybe empty, but my heart is laden
My sorrow is endless and I don't want to awaken

I want to see you now in my dreams, I insist
To dream that it is you I kissed
Now you are gone it's almost like I no longer exist
That's life, when things are good theres always a nasty twist

Please come to me soon, I will be waiting
My heart is aching.
