About a month ago I had a dream with my grandmother in it (she died in April 2016). The dream started off in a church. I was a bridesmaid for my friend's wedding (this friend is actually getting married in about a year). As the ceremony was ending, I noticed my grandmother sitting in one of the pews. She was alone. She looked like her usual self. In the dream she has not died yet. The ceremony ended and I was walking down the aisle to exit the church. As I passed my grandmother I waived to her. However, I noticed she was barefoot and her feet and legs were red and blotchy. I did not stop to talk to her since I was walking down the aisle with the rest of the wedding party. I did not exit the church, but instead turned around to go talk to my grandmother. As I began to walk towards her, her skin started to change. It started to turn red and blotchy, almost as if she was burning from the inside (it looked like her feet and legs when I initially saw them). In my dream this disturbed me so I started yelling at her. I told her to get out repeatedly.

I woke myself up and could not go back to sleep. I've been googling the possible meaning for almost a month and I'm not able to pinpoint it. My grandmother has never come to me in a dream before. Help please.
