Even the slightest thing can pull you back into forgetfulness. There you are, walking about aware of being a soul in a human body, when something happens to bring you back down to earth.  It does not have to be upsetting, but it does usually involve others.  One moment you are Peace in expression, and the next moment you know nothing of this state. This is why it behooves you to set the strongest possible intention to remain lucid.  Awareness will return sooner rather than later when peace and remembrance are the goal. 

You are so very loved.
