Kevin,

   What you dreamt is actually going to happen.  It is the GAMMA RAY stream that emanates from our own Milky Way galaxy's Black Hole.  This occurs every 26000 yrs. 8 mos. 3 days. when our Solar System passes through this BEAM, for a duration of 36 hrs.  Resulting in the entire Earth being bathed in it's radiation.  The effects of this are not being told to us, which in it's self tells us something.  This will happen (coincidently?!) on Dec. 21, 2012! .......MARANATHA!
