There is a battle of consciousness.
The amount of humans and therefore human consciousness is helping to accelerate and push a new level of conscious awareness to the fore. This creates a battle between old awareness and new. And has for centuries. It simply has become more intense as the numbers of humans rise and a fracture between realities becomes wider.
The amount of physical humans can not last even as new consciousness built over thousands of years now broadens out. For thousands of years small groups of humans have been creating methods to elevate human consciousness to another level. In this era, it is especially evident in Yoga and in Tibetan Buddhism. It is this sort of concerted effort over thousands of years that overall consciousness is beginning to peak in some of the population.
Music created a large rift in both human consciousness and that reach into alternate reality, especially in the way that it was facilitated in the 20th Century. It created a very large, if subtle, awakening, for many people.
What is now named Synesthesia is really only the tip of the iceberg of a widening range of those whose awareness and consciousness is changing, for that term is now including Empaths, those who Lucid Dream and have other experiences with Alternate Reality because the synapses in their brains are developing and expanding.
If humans survive the coming Storm, it is especially the Empath I look to survive. I believe it is the new tool of survival when applied with knowledge and wisdom. It tends to foster love and understanding as well as patience. It can be a difficult ability to master, but it can be. And its power is great.
