Right after my grandfather died I started having dreams about him being alive and everything being like normal or better but then the dreams always turned. I would feel a violent angry presence that absolutely terrified me and for whatever reason I knew it was my grandmother. Quite frankly I had never felt that kind of fury. I was having the dreams every night and was barely getting any sleep because of them. It became so bad that I finally said something to my mother. I suspected as she did that it was just grief and moving away from home shortly after his death. I thought maybe if I talked about it that they would stop. They did not. A few days later I received a phone call from my mother saying that my sister was having similar dreams only hers were focused on me instead of Grandpa. Later we found that our eldest cousin was, also, having the dreams. A short time after we discovered this we found that there was a mistake with my grandfather and grandmother's tombstones. They had to be swapped. Once the error was corrected our dreams stopped. I guess Grandma did not appreciate the mix up.
