Just read through this thread, decided to give it a bump in order to share my thoughts.

I think, and this is purely my personal opinion here, that DMT is a kind of organic technology, a crystalline retuner of consciousness, which raises the frequency of consciousness to a higher frequency, launching the human into a higher state of consciousness.

When I think of higher and lower frequencies/vibrations, I think of it like this. I think of it in terms of energy, which is consciousness. Energy which vibrates at low frequencies is moar dense and corresponds to lower, moar dense, moar material dimensions of reality. And vice versa for energy vibrating at higher frequencies. This does mean that lower is worse or higher is better,  it's all a spectrum, as has been stated previously.

Relating this to DMT, I think that what happens is, that when ingested, DMT raises the energetic frequency of the human consciousness, thereby raising the state of consciousness to a higher level. Graham Hancock, a man who I admire very much, speaks of psychedelics as "retuning the receiver wavelength of consciousness" an analogy which I like very much.

This. I think that the carrier wave is the sound of the "receiver wavelength of consciousness" being retuned. To a higher dimension, as you said.

Anyway, that's just my humble opinion.
