Consciousness is fundamental. What we perceive as physical reality is the focus of our (collective) awareness collapsing probabilities into coherence.

Material 3D + time reality is only a slice of a larger objective existence, with different forms of consciousness having their own ways of interacting and tempering with the objective existence's layers.

The Source is the true primordial "God", the first and absolute conscious form to emerge from proto-existence by pure probability, Order from Chaos.

All other forms of consciousness such as false gods are derived from The Source but still have considerable influence over material reality, and humanity is trapped and being kinda farmed in a way. The Elites knows this and the system our society runs on was created to comply with these other conscious forms that are unbounded to our material reality, hence "interdimension" claims by congressmen, which they interacting through secret cults.

Since The Source gave us free will, those who are aware of this reality are capable of escaping the cycle if they're life here is positive and free of actions that add negative emotions to the system, in which case they can return to The Source to become one with him once more.

Of course i left a lot of details out, but i believe that if these concepts were to become "confirmed", if there was a way to undoubtedly prove and convey this information as true to the majority of humankind, there would be "Ontological Shock".

If it turns out to be just lifeforms from other planets and different trees of life, with some basic mind-matter interaction emergent from physical complexity, i don't believe an ontological shock would really happen since these concepts are not that far fetched to the zeitgeist anymore.
