What Is The Meaning Of Seeing My Dead Grandmother Crying In My Dream?

That is so scary. I had a dream about my dead grandfather about 3 days after he died. He just told me that he is safe and has built a good realtionship with God and he seemed very happy.
Maybe your grandmother misses you, or if she wasnt a good person, maybe her afterlife is not so great. Thats just my guess though.
