Dream vs Reality

I dreamt of wrapping my arms around you, and smelling your hair
Drawing circles around your back, with so much care
And when I woke up, you were still there, lying on my arm
Away from pain, away from harm
But when I go to sleep, I'm all alone
I twist and turn, and moan and groan
And when I awaken, you're not here
So I close my eyes, and wish to disappear
