Dear God Lynne, there is so much here to comment on, so I might have to refer you to links.
The first thing I want to say is that your dream is probably not understandable unless you have certain information. We are all multidimensional beings, so have body sensations that are often quite distinct from our mental life. But often we may not realise that our mental life is also full of dimensions that are presented symbolically. We are like a landscape which if excavated is like an archaeological dig. It goes through right to the beginning of time. For instance you are probably not aware of all the life processes that brought you into being and still carries on caring for you. We usually call this the unconscious.
Because we are creatures created by the universe we live in, and despite much of the scientific arguments, we have in us all the levels of the universe, except our conscious self is such anew and vulnerable thing it shuts out what it cannot bear to know about itself. See
http://dreamhawk.com/inner-life/jesse-watkins-experience-of-enlightenment/So the beginning of creation was when there was not space and time. It was created. See
http://dreamhawk.com/dream-encyclopedia/archetype-of-the-big-bang/ It believe from that and people experiences and dreams, that not only do we have a sense of being a single identity, but also there is a level of experience in which we are all joined and so united. And the strange paradox of this and our inability to understand that paradox is what you see in your dream - “of people joining with one another. The gathering was on a large scale - like a planetary scale. We were gathering to work together and there wasn't total trust because we were all very different, yet joining together and choosing to trust was the only choice. Somehow I knew it was the only way forward and I wasn't sure how it would all turn out.”
Then the battle - “However, I was experiencing a strong feeling of being connected with all things. I had a deep sense of being part of everything, and of everything being a part of me. It was very real and I had a spontaneous image of standing in a great garden, an immense place of creation and unity – the Garden of Eden feeling. As this happened I had an insight that most of the people in the world do not have, and perhaps do not want to be a part of this unity. This thought, in the way it was experienced was completely new to me. I couldn’t understand why anyone would not want to experience this wonder and communion. I knew I was at the wedding feast, the celebration of life or creation. It was a wonderful feeling to be a part of this mystery. Therefore the realisation that many people did not want this was slightly shocking or unnerving. It made me ask myself the question of whether I was naive, perhaps not seeing or realising something. This realisation went on to the sense that in fact a sort of battle was going on between those who were part of the celebration, and those who didn’t want it. I thought that those who didn’t want it were perhaps frightened of losing the control they thought they had over their life and the world. I knew I was playing a part in this battle or struggle”.
So you are not alone in those feelings. Many people are experiencing such. Also the unicorn was a creature from another planet. The unicorn is similar to Pegasus the winged horse. This symbolises the sexual or instinctive drives that have not been repressed, but allowed, in conjunction with consciousness and reason, to develop the higher possibilities latent in us. Put in plain language this suggests that the sexual drive rises like a wave that carries our conscious desires with it. This energy wave rises, but in fulfilling itself in genital sex the wave falls again, self-awareness with it. However, if the energy is released, and yet not allowed to spill out in the full sexual release, the energy keeps on rising – flying in fact – lifting awareness with it, until it becomes a vast awareness of life and death. Observation of this suggests it awakens parts of the brain that were not really functioning before.
Also the other planet may have another explanation as well - remember the paradoxical nature we all share - “The plan for the earth cycle of souls was a series of incarnations, interlarded with periods of dwelling in other dimensions of consciousness in the system-the planets, until every thought and every action of the physical body, with its five senses and conscious mind, was in accord with the plan originally laid out for the soul. When the body was no longer a hindrance to the free expression of the soul-when the conscious mind had merged with the subconscious, and the atomic structure of the body could be controlled so that the soul was as free in it as out of it - the earth cycle was finished and the soul could go on to new adventures.” Taken from the philosophy of Edgar Cayce, see
