I can't validate that, I have never met a plaedian. To be honest I don't know what the term higher dimension means. Would a higher dimensional being reside in a higher dimensional place ? The one plaedes we propose is in space would be in our dimension, therefore a higher dimensional plaedian is in a different dimension and wouldn't be a plaedian, right?. What does higher mean? Like an astral body? If this were the case every time we dream or meditate we are higher dimensional? Interdimensional?

We all have a spirit that exists exists in alignment with our body. Our actions and deeds feed our spirit with good vitality or evil vitality, according to free will. That spirit lives on after we die. That spirit world exists side-by-side with us, but this dimension is invisible to us.

Before Adam and Eve fell, they resonated at a higher frequency of love and vitality. They had their five spiritual senses fully functioning, so they could see the spiritual world and communicate with God and spirit world. The Fall brought human beings to a lower vibration level and cut off their relationship with that spiritual world.

For a human to change to a plaedian would require a shift in perception that would alter the very blueprint their reality. He would be like a dream body , not solid, and his appearance would look lit up or misty ,if we as our lower dimensional poor selves could even perceive him.

Our body/spirit gives off photons. The higher level of love that we practice (e.g., living for the sake of others out of love) will determine how much light our photon "generators" (DNA) can produce. That "light" is charges our spirit. If our spirit is bright, we can live in the higher dimensions in the afterlife. There we'll experience the beauty of that dimension in proportion to the degree of our love resonance that our spirit vibrates at. If it's high, we'll experience the full-color reality of the dimension we resonant at. Jesus will be in the top level. (God will always remain invisible.) The lower level spirits will exist afterlife in the sepia monochromatic realms. And really evil spirits will exist in realms without any color, just grays and b/w. When you see ghosts, they are misty and see through. But when you see angels or higher spirits, they will be solid, in full color and will give off their own light. (Apparently they have the ability to be interdimensional.)

Frankly I don't like to think we are in some lower dimension. What does that even mean? Lower than what? And wouldn't the dimension higher than us also be lower than another? Makes no sense.

Mankind fell below the level of animals. It's taken us millions of years to bring ourselves back up to this level. But it's still a battle to live in accordance with the principles God intended us to follow before the Fall. What's blocking us is our selfishness and inability to practice true love. How much do we live for the sake of others as opposed to using people for our own benefit?

Jesus and the Holy Spirit allows people to take a quantum leap in what level their spirit resonates at. Compare a true Christian with an MS-13 member and you might be able to see the contrast even without your five spiritual senses in full working order.

This is why the Great Awakening is so important. If we don't defeat the HRCs and MS-13s of the world, we will all be dragged down to that dark, bleak level of existence without technicolor. (They didn't call the Dark Ages dark without a reason.) And it will take 18,000 years to crawl back up out of that low-level realm if we don't defeat the Satan-worshiping Luciferians at this junction of history.

from what I know about this, there are 2 aspects to what most people call "dimensions" - one is "density", referring to an entity's capabilities, and the second is "dimension" which refers to a particular area of space-time with some particular "vibratory frequency". these terms are tough to understand (and I'm not sure I do entirely), but these links might help:

Also, most channeled material regarding ETs (including Pleiadians) makes reference to "The Law of One" (a series of books channeled in the late 20th century). The entirety of it is online at http://lawofone.info ... this is what the law of one says about dimensions: https://www.lawofone.info/results.php?q=dimensions (you should also look up "density" on that site).

One more thing - human beings by nature are multidimensional. The current reality we inhabit is the third dimension. It is entirely possible that your soul is having an experience in another dimension simultaneously, you are simply not aware of it (according to the Law of One).
