For example, I like to indulge in a personal theory of mine that explains deja vu. I call it t3mP0r4l H@rMonIx. Because I have a fair amount of experience using the and understanding the electromagnetic spectrum. Thanks to my bit of time in Military Intelligence, I understand that radio signals having harmonic resonance.

Don't take the image above literally, it's just for instructional purposes. The bottom line is if you transmit a signal in the above image at 7.83hz you get resonant 'bumps' at the other spikes you see (14, 21, 26, so on and so forth at degrading strength in both directions along the spectrum). So you can passively collect or jam radio signals by operating on other signal frequencies that correspond with one you want to target. It's pretty neat.
My 'temporal harmonics woo theory' postulates that nothing is truly material, that we're all fundamentally composed of forces and energy transference between forces that give us the illusion of materialism, but when you break us down to our fundamental 'stuffs' there's nothing really there. So, to get to my point, I think because we're energy and force we have temporal signals throughout the various dimensions and that occasionally our harmonics match up nicely and we see or do something that harmonizes our existential experiences and causes us to feel that sense of deja vu. For example, if you believe the 4th dimension exists then space AND time in toto exists and it wouldn't be unusual that a temporal harmonic from point 'A' over there syncs with point 'B' over there even though linearly they're separated, but temporally they're actually operating on the same resonant frequency.
So. If you're still with me I think this is what's going on with you:
I think you sense a lot of things that can't actually be described as of yet and you're attempting to paint a picture that makes sense with your brain given your cognition, education, and capacity to think abstractly.
For example, I'm not sure if you heard about Kaluza-Klein theory. When I was attempting to wrap my brain around the KKT basically is a component of the Unified Field Theory, a precursor, I believe, of string theory (it may set ST up as a possibility) which is a huge step toward the Grand Unified Theory, which admittedly I only have an interest in because I was married to a burgeoning theoretical physicist who had made it her life's mission to be the first person to produce a workable GUT.

So, I think you intuitively are experiencing things and interactions, like the 5th dimension, or the 4th, or whatever but simply lack the 'pictures' I provided above to make it make sense to your particular brain. You intuitively know there is more to the universe than purposeless matter bouncing around, and so your brain is manufacturing, like my temporal harmonics woo, answers or theories that make sense to you. I think it's great you're thinking about this stuff, and as a result you generate interest in the science behind some of the really interesting theories out there at help us discover how reality possibly operates. I think about it, too.
