The Ghost on Christmas Eve

Nico Shiasians saw a figure standing right in front of him on Christmas Eve. It looked almost as tall as the Christmas tree and appeared to be wrapped up in a white sheet like you would wrap up a body before burying it. He thought it was going to be Santa Claus, but he wasn't scared despite the fact that this was the first and only paranormal thing that he ever witnessed. His girlfriend said it might be a guardian angel since it woke me up from a nightmare. The prospect of seeing a guardian angel has my mind reeling with questions of religion and afterlife.
