A belief you have or used to have

I have never believed in God, or astrology, or anything to do with superstition or myths. However, when my grandfather died on my mother's side, I began to notice his presence around me even though he was already gone. 

Of course, I can't see him, but still, in the moments when I need help the most, in the nights when I cry, etc. I can feel my grandfather is there for me, by my side, encouraging me to go on.
