A Backrub

Late one night I was laying on my back on my bed. It was a short time after my great-grandmother died. I was laying there trying to go to sleep when I felt something on my back. I looked around and the cats weren't in my room and neither was my mother. I put my head back down and this thing on my back began to give me a backrub. I wasn't afraid. It was like something told me it was alright. I continued to lay and eventually it stopped. I'm not quite sure what that was that night, but I believe it was the spirit of my greatgrandma.
