How a vision begins

It begins in dim lighting, with few hours of sleep.  Something moves in the peripheral of your sight.  You turn to focus, it is gone.  You try to chase it and it moves further away.  It gnaws at your guts, pulls you from sleep, drains the power from other thoughts...
It will consume you until you take action.  You must appease the spirit, give it a life of its own.  With sweat, blood and the required swearing, you weave the spell of life.  Then the vision grows, infects more of your day and leaves its comfort of night.  The vision shows you yourself.  It was never its own persona, just a part of you that wanted to live.
