We all share the same planet, but I believe everyone has its own dimension, its own world, its own group of friends. I believe that each one choose the universe where they want to live. Even unconsciously, we attract and perpetuate the things we have around us by choosing them. For some reason, that particular choice teach us something, even if we complain about our reality all the time. If you're ready, you can change your dimension without notice it, like the old Mayan culture predicted it.
When you feel that something is wrong around you; that the people you meet is not the people you wish to have close to you, then you have to start making changes. If you don't want to make radical decisions about it, or make any change that move you from your comfort zone; whether you like it or not, you still need to be surrounded by that particular situation or relationship you don't want to.
I believe that, because I'm connected with people very similar to me (even on internet!) sharing the same points of view and trying to be better through a spiritual path. I had to fight to move out of my comfort zone, but I'm glad I did it. Also, I have been having vivid dreams about life and other portals where I can fly, float and move things with my mind. I truly believe that the Mayan culture wasn't wrong about all the things they said... I think that they were just misunderstood. The change of dimension is individual, not massive.
If you've read me until the end, we may be sharing our own dimension or you're near to change yours...
