Studying the dreamtime begins at a whole other level. There is nothing to conventionally explain the purpose of dreaming or why they occur, but there is a reason for them. Perhaps you do you not understand on a conscious level, but on a subconscious level... you do. One must remember, when dealing with the subconscious, you are transcending all realities, all language barriers, linear time, and all realms. You can experience multi dimensional realities simultaneously. Communicate with telepathy and symbology that in our earthly world, we maybe equate to simply being cryptic mumbo jumbo. But secretly, you and I both know that nothing is just random when it comes to a subconscious level of existence. There is always method to the madness. Its simply that our human minds cannot comprehend a bigger picture... a higher, more intellectual intelligence. But as you become more aware and more conscious, the understanding may become easier.
One way is to begin to start making a journal of dreams and your daily lives. As soon as you wake up, try to remember all of your dreams and record them immediately whilst still vivid in your mind. While it may not make any sense whatsoever, you are doing something very valuable and important. You are telling the subconscious that you are wanting to remember and retain this information on a conscious level. Thus then, you will begin to understand... translating your dreams from a subconscious level into a conscious level. A conscious level that you can understand, and perhaps make sense of. Dreaming intermingles with metaphysics.
The study of metaphysics is a tricky one, and not one for the faint hearted. What happened if I told you, you can reincarnate into any form of consciousness existing? To be a leaf or to be a cloud? Or that many of your so called past lives, are simply 'imprints' that you have borrowed from someone else's experience and applied them by stamping them onto your soul without even physically experiencing them? What would you think if I told you that if you began walking into one dimensional reality down a street, and then suddenly you bleed into another dimensional reality without even knowing it? Metaphysics gets more and more complicated. So keep it uncomplicated, take it with an open mind.
Sometimes higher information can be poison rather than medicinal if one is not prepared to hear it or handle it. Your subconsciousness will only allow you to be exposed of the information and learning that you are able to handle. So take it with baby steps, learn and flow with life in its simple and illustrious ways.
Simply flow... and follow your heart.
Start writing down your dreams to recalibrate your physcial mind to have a broader perspective of All That Is and the ever-enigmatic awareness we dare to call consciousness.
