Why is it?

Why is it,
I dreamt about you last night.
When I had other worries on my mind?

Why is it,
I remember every portion of that dream,
where we were, and what you looked like.

Why is it,
in this dream you whispered in my ear,
and I can still hear your sweet voice,
and feel your breath upon my neck.

Why is it,
in this fantasy world I felt your arm around me,
and I can still feel it to this moment.

When your in my dreams you steal my breath,
you take all sorrows away,
and put them on a distant star.

I smiled as I awoke from this world,
and was saddened by the realization,
that it was just a dream and not reality.

I try to go back,
to resume this world and live there forever,
but I can't and my heart aches.

You play with my heart,
and make me cry without even knowing,
why is that?
