Sadie - Yes we are all going to die, but we are doing it all the time, and sometimes it is very dramatic and marks the end of an old way of life. Your dream indicates a wonderful transition.
In every moment of our life we face the possibility of death. In fact we only live because we are constantly dying. Our body is all the time dying as thousands of cells die, and in doing so the new and living body can continue. If we allow ourselves to realise that, it illustrates the meaning of the phoenix – it is consumed by the flames, and yet it arose anew. We have the fire of life within us; we eat and feed the fire that consumes us and gives birth to us continuously. It is the warmth of our body, the warmth, even passion, of our emotions and that is Life – continuous through death.
Example: This was not a dream, but a direct perception during sleep. I saw that a large part of my being was dying, and another part coming to life. Andy
Your looking at the stars in your dream shows you seeing beyond the everyday fear of death and seeing the grand and underlying cosmic forces which are part of your being.
I believe you have the ability to move beyond the images in your dream and know what they are an expression of for yourself. Therefore I suggest you try imaging yourself as the stars, the space and the moon. Be the stars rather than simply looking at them, and do not try to think about what they are because dreams arose before thinking. See
