WRITER'S NIGHTMARE""I felt a grip on my arm that shook my body, forcefully pulling me toward a tunnel of darkness.   The threat of consciousness stole my steady breath. For a moment I believed myself to be under siege; ripped from the sky in mid flight, my wings useless against the monstrous claws shredding my reality. I struggled to remain, to be left alone, aloft.  Reaching with wings that through the power of imagination were suddenly feathered arms, I grabbed at the air.  My hands clutched at something solid.  Wooden.  A desk.  My head spun as I held the furniture, suffering the illusion of falling.  "I was flying," I gasped, realizing suddenly that it had all been a dream. "My best fantasy ever." Lifting my head from its resting spot on the writing desk, I worked mentally to secure the fading images, hoping to capture their essence to memory before they faded away forever.  Bitterness tainted my heart against the hand that had jerked me into sensibility.  Why was I always so callously awakened while doing my best work?  Why not let me dream?
