What do you think this dream means?

Ok so in my dream I was on earth at first then I was on a spaceship there were several people with me that I don't know but I seemed really familiar with them in the dream they looked different somehow taller. We were going very fast and I remember watching the planets fly by then suddenly we were in space it was dark and we went into some sort of black hole type thing I saw us heading up towards what looked like light in the distance (I felt a feeling of doom like where are we going) I saw what looked then we came another solar system (going very fast) there was a huge blue planet on one part and one with a more purpleish hue, we went to one of the ones closer to the star. When we landed I kept looking at the sky fascinated with the fact that it was a more deep blue color (almost purplish) and the clouds looked different somehow. There were streets and businesses and houses there but they seemed very different from the ones here on earth. There seemed to be symbols and other things that I wasn't familiar with Also as it got dark I was watching facinated the sky and the clouds parted revealing a very different star formation it was much more bright and there were countless stars clustered together some blue some white some yellow I was looking at a far off galaxy and there was kind of these blue and green flashes in the sky as it got dark. Suddenly I felt a sense of urgency and people were leaving the streets going towards their homes and someone told me you got to go you can't survive how cold it gets here at night. Then I woke up.
