Sleep Patterns

Sleeping, or waking,
Or drifting between.
Tired all day,
Or up all night-
Neither matters.
Sleep is never enough
Sometimes I just give up.
At times, I can't find it,
At others, it chases me:
The dreams follow.
I dream of before,
Or what could be.
Of what I wish,
Or what I dread;
What I know isn't real.
And it scares me
When I dream of things
That might.
Are they unreal?
Or could they really be?
I don't even know
Which I want to be true.
My heart is torn so easily
Between sanity and fantasy.
