unusual dream-need opinions please?

I had a dream last night. I was at some kind of picnic/potluck and my sister was there too. She was at a table with another person. There were a couple baby shower cakes in front of her and she was talking to the woman about making a baby shower cake for someone. (I decorate cakes) But she was going to make this one. She kept poking the cakes and messing up the decorations. I offered to give her my recipe for icing since she's never picked up a pastry bag, but she was rude and said no.

I walked off, a bit hurt and just walked away from the picnic. I was wandering aimlessly through a vacant dusty field, tears in my eyes. I remember feeling the dirt getting into my sandals as I was walking. I looked up and there was a young college age man videotaping me. He said he was doing a project for class and he needed to video someones feet walking just the way I was walking. I figured what the heck and let him continue. I walked across the field again, then watched as he replayed the tape. What I saw was a bit shocking. It was pictures of a woman's feet, but with blood vessels all over them. Then I saw the face and it was a young woman, very pale face, dark hair and the same blood vessel tracings all over her face, like a horror film. She didn't look scary, but rather sad and pensive. I realized then that I was providing the movement for the film, and he was transferring it into animation for the film

At this point I woke up.

Any ideas of a possible meaning? Thanks for any and all ideas.
