Dreamtime - Thanks for sending me this fascinating dream.
I see it as showing your further transformation of the Christian background you were born in. The part about your cousin Christine, who represents an alive and beautiful part that left behind the ideas the church has, and felt the life in you - a sort of rejoicing in being alive - the real Christ-in you.
But there were still thing that needed to be faced. The kittens represented the new and lovely life that can flower as you grow. The poison may relate to what your mother took in, but you are aware of it and how it can kill the youth and playfulness of kitten-hood. You hope your mother will reject it.
I believe the barbecue is almost like a very ancient form of socialising, where fire is still used to cook food outside. It is like the cooking pot on the small fire outside the hut. But the meat, physical experience was lost - possibly showing a change in yourself for different food. Instead of food for the body it becomes spiritual nourishment. See
http://dreamhawk.com/dream-dictionary/spirit/The white twins you need to explore to be certain, but they are carriers of the white light, and might even relate to Gemini, the twins. But the colour burgundy is like red earth, but richer and deeper. It feels to me like the wonder of discovering the deeps within you, and the kitten is a living part of you.
But you have such a variety of ‘colours’ that are growing in you, showing you can respond to life, events and people in a variety of ways.
