How can I ever know!!

I think of you at times
And sometimes quite often,
Like tonight, now and last night
I dream of you at times , during
          The day
With my eyes open and at night
When I cannot sleep.

But how can I ever know
If you think of me at times
Like tonight, now and last night
Do I ever walk with you during
            The day
With your eyes open and at night
When you sleep?

How can I ever know?
