  Are you sure it was snow that you saw in your dream?
 
  Ash from a volcanic eruption could look like snow (that area of the world is volcanically active).  Link to USGS info about volcanoes in/near Greece:  http://vulcan.wr.usgs.gov/Volcanoes/Greece/framework.html

  Ash, dirt/dust, and debris from a large explosion, dirty bomb, or nuke could also look like snow   (the Olympics are considered a potential terror target http://www.fas.org/irp/crs/RS21833.pdf). 
 
 WWII Nazi concentration camps rained ash from the ovens burning Jews, Gypsies, etc.that was described as resembling snow.
 
  Tis the time of year for meteor showers...
 
  An avalanche could cause a short-term white-out...
 
  Some interesting facts about snow/man/Jesus:
 No 2 snowflakes are the same (just like people or fingerprints)
 Snowflakes all have 6/multiples of 6 sides/points (and 6 is also the number of man)
 Snow is white because it reflects most of visible light
 Jesus' head & hair are described as being white like wool, as white as snow (Rev 1:14)
 Jesus' rainment is described as being as white as snow (Daniel 7:9 Mt 28:3, & Mk 9:3)
 The saints' robes are white (Rev 6:11, 7:9,13, and 14)
