I guess the interpretation, whether it should be taken literally or metaphorically depends on the context of a particular biblical verse. For example: Mark 16:18 they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well." If I am to take that literally, that verse states that I am immune of poison (because I believe in Christ), but of course there are no Christians that are immune to poison just because they are Christians. In the Catholic denomination, we seek the teachings of the Church so that we'll know when a particular verse states something symbolical or literal so personally, I'm not having much problems with this.
There are two endings to Marks Gospel The shorter ends befor 16:9 the other longer version ends after 16:19.
The Passage you gave is in the longer version only... It is not clear if both endings are new material added to make up for the missing end of the scroll. ( both the beginning and end are missing)
However the long ending does have rather a gnostic feel that is not out of place.
