Greetings
Interesting Dream, I too am curious about deciphering dreams.
From looking at yours ; there are a few things I can pull out of it
You mentioned a new sign. This is what I believe to be Ophiuchus ; which in the media was released as the 13th "New" Astrological sign in between the dates of nov/dec.
Despite the media news reports that were recently released about this "New 13th Sign" ~ it is not a new sign. Its actually just a debate between Astrologers and Astronomers. (if interested in this more I would be happy to explain further)
As for a War. We are in it now. I don't know what part of the world you reside in, but from my travels and experience this war has been going on for quite a while. A friend who learns lessons from his Shaman, expressed that he told him of a path that Humanity would need to chose. We must chose to follow the Ascension, Rebirth and the Dimensional Shift. There is a growing amount of Scientific proof indicating that our Solar System is in the midst of a Shift. A excerpt I'd like to share from ; http://www.bibliotecapleyades……he%20Shift
"Many native tribes in Mexico and South America believe that Galactic Center or Tula emits a frequency or tone known as Ge, and that this tone not only heals the body and mind but brings immortality. The spiral Ge shown here represents the frequency being transmitted from Tula or Galactic Center.
I believe that as our Sun, Earth and us move towards the big conjunction, that this frequency is getting much stronger.
It’s vibration is activating our DNA and metamorphosizing us from being humans. Russian scientists have discovered that the 
97% empty space in our DNA isn’t empty. They believe it is filled with something called torsion wave energy. I believe that this energy could also be called love or even the tone of Ge.
Scientists now believe that torsion wave energy not only exists before the DNA, that it actually tells the DNA what to do. Our DNA is a hard drive. Torsion energy/LOVE/tone of Ge interacts with our soul and heart.
The energy from our soul and heart organizes the torsion wave energy and tells the DNA how to arrange itself. This creates not only our physical body but our whole REALITY. I believe that the ancient Mayans and other indigenous people knew and understood this."
Changes in our Solar System ;
SUN: The Sun’s magnetic field is more than 230 percent stronger than it was at the beginning of the 1900s. Its overall energetic activity has sizably increased, creating a frenzy of activity that continues to embarrass NASA’s official predictions.
VENUS: is now glowing in the dark.
EARTH: Beginning about 1960, Earth’s surface grew dimmer by 4 – 6 percent. About 1994 it began brightening again, which scientists believe may be accelerating global warming and the greenhouse effect. During the last 30 years, the icecaps have thinned out by as much as 40 percent. For reasons that scientists are unable to explain, in 1997 the structure of the Earth began shifting from being more egg-shaped, or elongated at the 
poles, to being more pumpkin-shaped, or flattened at the poles.
MARS: This close-up image of Mars (right) shows how its icecaps virtually melted within just one year, causing 50-percent changes in surface features and its atmospheric density has risen by 200 percent since 1997.
JUPITER: Jupiter has become so highly energized that it is now surrounded by a visibly glowing donut tube of energy in the path of the moon Io, which now glows in the dark. The size of Jupiter’s magnetic field has more than doubled since 1992.
SATURN: Saturn’s polar regions have been noticeably brightening, and its magnetic field strength increasing. Between 1980 and 1996, the speed of rotation for Saturn’s clouds at the equator reduced by a whopping 58.2 percent, which was an unexpected and dramatic change in its weather.
URANUS: In 1999 NASA articles were referring to Uranus as being hit by Huge Storms, making it a dynamic world with the brightest clouds in the outer solar system. NASA also said that if springtime on Earth were anything like it will be on Uranus, we would be experiencing waves of massive storms, each one covering the country from Kansas to New York, with temperatures of 300 degrees below zero. NASA’s Voyager II space probe indicates that both Uranus and Neptune appear to have had recent magnetic pole shifts – 60 degrees for Uranus and 50 for Neptune.


NEPTUNE: Since 1996 Neptune has become 40 percent brighter in infrared and is 100-percent brighter in certain areas of its surface (right). Neptune’s moon Triton has had a “very large percentage increase” in atmospheric pressure and temperature that is comparable to an increase on Earth of 22-degrees Fahrenheit.
PLUTO: As of September 2002, Pluto has experienced a 300-percent increase in its atmospheric pressure in the last 14 years, has also become noticeably darker in color.
As I was expressing earlier in the first paragraph, we are Ascending ; to move upward, and grow. There is a path that we are being faced with (every day humanity is faced with challenges, and distractions that pull us away from our heavenly selves, it is our time to exhibit self control and help others if we can and wish to do so.)
This path is either good, or bad. The good path resulting in harmonious actions, unity, and love for the earth and brothers/sisters. The bad path ; those who are so influenced by materialisim which leads to corruption and hate, and the negative distractions from the 21st century that draw AWAY from our pure innocent selves. I see this path in front of my eyes and soul daily, I see what his Shaman spoke of, and I see people being sucked in by the bad path, and those who are able to rise above and even help others along the way.
So for us all on this forum, I know we at least all have such a wonderful idea about living and the earth, LETS DO IT. Lets get off our computers, and take action. Encourage unity and love for humanity and the earth all ways possible.
Our character and personality is a gift to us all to help heal and teach others.
I honestly feel like your dream was reaching out to share this message with you.
You mentioned a Box in your dream that you receieved. Dream interpretation states that a Box represents things you store inside you, such as memories or emotions. A closed box can represent the womb, or things you hide from the view of others or even yourself. Depending on the size of the box, it can represent memories, or treasured experiences.
Black. This is the colour of the night, and so because it links with absence of light, opens us to what we can’t see or deal with in the dark – in what is ‘in the dark’, unconscious – within or around us. It is the experience, like sleep, in which the ego diminishes or melts back into unconsciousness. This relates to all those things you repress or avoid feeling or being aware of in yourself and life. So the dream will probably include threats of some sort, or what is unknown, hidden or avoided. So this relates to your hidden fears or past hurts that have been buried and remain unconscious.
I believe that you should look deeper to yourself, and make sure that your healing is complete before healing others. (No disrespect at all! This is factual) We as human beings, and souls MUST make sure that we are healed ourselves and in the right state of mind before helping humanity and others. We must protect our emotions and our selves ; in order to feel others energies and help them heal as well.
The moon symbolization. Possibly depicts the break up of hopes or fantasies which do not connect with reality. For instance breaking free of external limitations to connect intellectually and deeply with mind, body, spirit/soul.
As for the visuals of other beings, I believe that the more humanity ascends positively, the more open our mind and souls will become. Learning how to open our third eyes is one way we can open our eyes to the other beings and spirits. This is your Third Eye telling you its longing to be opened.
From this dream, I interpreted that you are aware of the shift. Your mind is reaching out to you in your dreams, and sharing messages and visuals with you. Look at the things I wrote down and try and relate them to your life and be as HONEST and open with yourself. Do not be in denial about anything. Come to face Reality as it is. Realize the WAR is taking place in front of our eyes. Do what you can in your community, and world. Start by sharing love with a human and displaying peace. A simple act like that can astonish a human who has never felt that before. (From experience)
Pick up trash anytime you see it, clean the earth. Share thoughts and emotions with people. Represent yourself and stand up for your beliefs! Exploit how important it is to be here in the NOW and respect Mother Earth for whom she is.
