< how our consciousness interacts with spacetime.
As it is defined (to my knowledge), the 3-D experience that we are having is already a part of space-time. Ergo, anything that you do, think, perceive, is already a part of space-time. I think the real mystery resides in the dimensions above (possible below) those three/four dimensions. Time is often refered to as the "4th" dimension. This might be an example of an emergent property. As in, when you combine Versicle, Horizontal, Outwards... A new dimension emerges from that 3-D space to provide a new sort of "depth", which is what we call Time.
It is plausible that this emergent interaction occurs whenever dimensions are combined . Another reasonable view would be that we are actually looking at this from the wrong direction, and we only observe this "Bottom to Top" building hierarchy because we happen to be at the bottom. Perhaps, we are only limited to our personal view-point, and the whole dimensional spectrum would look very diferent if we were somewhere in the middle. As in, we might only observe dimensions 4-7, or 8-14. I don't know since I don't exist in those dimensions, but it is possible.
I must have started rambling, sorry...
Anyway, by definition of "space-time", your consciousness is a part of space-time, so naturally, it is already "interacting", if that makes any sense??
< I've come across mentions of people being able to produce certain brainwaves, maybe those have an effect if produced in high concentrations or at high power or frequencies?
See above ^
< If that is the case, maybe there was a physical purpose for Gregorian chanting and other similar religious traditions, not just spiritual?
As I have explained...
Spiritualism, even if it happens in your brain (which is a part of space-time) would naturally be causing effects in dimensions which are beyond your typical 3-D reality.
You wrote diferent which should have been different
You wrote refered which should have been referred
