MK – This has a similar theme to your last dream – the death of someone. Also any small soft and vulnerable creature is usually about you as a baby.
Because in our dreams we are dealing with unconscious feeling, memories buried under the silt of years, you have not got not meaning for you in your adult form – the man. Remember that when you are asleep, there is nobody else there but you and your mind. Unfortunately most people feel that what they see is real, and not the magic work of their brain. So when you dream about someone you know, or a frightening monster, what you are experiencing are images the brain uses to convey something to you. They are all you - your fears, your inspirations, you sexual desires or fears, your feelings and intuitions about the dead, even you predictions about the future, are all your own creations.
A long time ago you were coerced into sacrificing a part of you, and she, another aspect of you, had no idea what you had done. But at the moment you are beginning to feel it consciously, although it felt right at the time.
Ask yourself what you have done? And listen for a reply.
The crystals are usually a deeply buried part of you. Remember that your conscious self is only small surface thing. It depends upon all the unconscious processes of Life to keep you alive. And a part of the unconscious is all the levels of your body, from crystallised formations through vegetable and animal. I feel that the crystals are giving you something that is difficult for you to understand. But you can grasp the meaning if you try. See http://dreamhawk.com/dream-encyclopedia/acting-in-your-dream/
I feel it is saying something like, “We crystal have been here for a very long time, and we have a lot to share with you, who are lost in the difficulties of change and time. So hold us and remember.”
