DS Star,
Very interesting topic. These dreams seem to point to the end of the world by the fact that some of the things interpreted by the Buddha seems to be happening. That is quite obvious.
However, in Buddhism we take the Guru and the 3 Jewels as the refuge and the Dharma Jewel is the main refuge in that it is the practice of the Dharma that can actually transform one from samsara to ultimate enlightenment.
If that is true, then we need to practice the Dharma more than worrying about the end of the world which is beyond our control. Moreover, if all that is interpreted is true, then, we can safely say the truth of suffering is more prominent now than ever and we should take that as our motivation to generate boddhicitta to benefit others. I personally see that sufferings in many forms everyday.
Lastly, the "end of the world" is relative. The only thing we can be sure is that we will all die one day. It can be the next minute or the next tens of years. I bet the world will still be around when we die. So meditate on death be it from the natural expiration of our lives or from the "end of the world"; at which point we will die as well.....! So practice the Dharma!
