Tom Montalk on the Densities.
What about the reported shift in consciousness that occurs when you enter a 4th or 5th Density environment, is that the same as becoming a 4th or 5th Density being?
If you were to take the soul of the average animal and give it a human body, it would now have access to the human intellect and be able to learn how to speak and function in society. With an upgrade in biology comes new tools, in this case physical/neurological ones. However, this humanimal would be a rudimentary human with no wisdom under its belt, no higher spiritual priorities, and would likely be preoccupied with personal survival and reproduction because that is all the soul has known so far. Thus it would experience an altered state of consciousness due to a different body and better brain, but at the core it would remain a 2D being.

Likewise, when a purely 3D human is brought into 4D via abduction, psychic, or technological means, he would experience an altered state of consciousness but remain 3D at the core. The change in consciousness comes mostly from an upgrade in his etheric body circuitry, due to etheric currents being shifted and heightened within him, which in turn is due to the 4D environment being denser with such energies. This etheric activation enables certain psychic functions that allow bypassing some of the limitations of the physical brain. He or she would feel lighter, more alive, be able to comprehend much deeper and wider thoughts, and be able to perceive and remember things that otherwise are inaccessible.

But until he lives there for a long time and learns the gamut of lessons unique to 4D existence, he would remain a 3D being at the core. And when he is brought back to 3D and his etheric energy subdues back down to base levels, all of that fades away and he might even forget his experiences there, for they were perceived and recorded in a portion of his being other than the physical brain into which he is now locked.

Similarly, if a 4D being incarnates into a 3D human form, or projects itself down into 3D and becomes fully physical for far too long, the 3D environment and laws of physics would begin impeding this being’s formerly high caliber abilities. Like a plant cut off from light, it may enter a kind of spiritual sleep, a kind of stupor or amnesia. In a sense, a former ‘god’ becomes a mere ‘mortal.’ At their core, they will still be 4D but they will now be subject to the entropy, inertia, and handicaps typical of 3D environments and bodies.
And when a person dies and goes to the 5D afterlife, in being freed from the restrictions of biology, linear time, and space, he would now have an expanded level of perception but still only have 3D experiences and wisdom gathered at the core of his being, with more to acquire in further 3D lifetimes.

Now, the tricky part is that not every human is necessarily a 3D soul. If a 4D soul incarnates as a human (say, as part of a humanitarian mission) then if this person were brought into 4D during an abduction, he would return to his former self during his stay there, instead of merely being augmented with foreign abilities. In fact, these abilities might feel familiar.

Similarly, when a 5D being incarnates as a human and later dies, its entrance into 5D density is not merely a temporary sitting down at the sidelines in between incarnations, but a return home to the nonphysical realm it natively inhabited before coming here.
So there is a difference between having your consciousness altered into something unnatural to your level of evolution, versus having handicaps lifted and returning to your true self in that higher density.
