(This has details of my nightmares, so please don't read it if you find that sort of thing to be upsetting. I don't want to upset anyone)

My best friend passed away suddenly a few weeks ago, and I keep having these nightmares about her. I'm losing a LOT of sleep because of it, and the images from my nightmares stick with me all day. Last night I dreamed that I was at her funeral, and she was there in the casket. Her body was laying as if someone had just dumped her in there and I could see her skin turning black on her fingers. No one was recognizable, and there were two elderly women kneeling by her casket and praying. Suddenly, her body shifted and she sat up. But, she wasn't alive. They forced her back down and walked away. Somehow we were at the cemetery next, and it was time to bury her. But, her casket was still open at the grave-site. Suddenly, her body shifted again, and she once again sat up, but this time her eyes opened and she looked at me. No one noticed or even seemed to care. I turned and walked away, and somehow the cemetery was along an ocean beach. I got onto the boat with her mom and her son, and we set off towards the horizon. I looked back and she was watching us go, with her hand reaching out to us. She just sat there in her coffin, obviously dead, but very much alive. No one else noticed or seemed to care. I began calling out to her, but no noise came from me. That's when my husband woke me up and said that my screaming woke him up.
All day long I've had these images of her like that. Her flesh rotting and her eyes looking as though she were still alive.

Other dreams I've had were worse, and some just bothered me, but I wouldn't call them disturbing. One I've had several times was her and I standing at the cemetery and we are about to hug each other. Just as I do, she turns into mist and is carried off into the wind.
