Humans have an energy for sure, if nothing more than EM. Probably/possibly something more to the soul that is unknown too. I've never seen an aura. I don't think that there's equipment that can "see" an aura.

In theory the reason that we "get a bad vibe" from folks is more about the reading of cues, body language, etc..., but there could be more to it.

I personally feel that the "vibrations" thing is taken a bit too far. Yes, atoms/matter moves, but I don't know that I think that's causing anything extra.

There are people that have extra cones in their eyes (most of us have 3, there's an idea that some women have 4).

Maybe it's tetrachromats that are the ones that are "seeing auras" (any time I've heard of it, it's always women).

The typical person has three types of cones in the retina that allow them to see various colors on the spectrum:

Short-wave (S) cones: sensitive to colors with short wavelengths, such as purple and blue
Middle-wave (M) cones: sensitive to colors with medium wavelengths, such as yellow and green
Long-wave (L) cones: sensitive to colors with long wavelengths, such as red and orange

This is known as the theory of trichromacy. Photopigments in these three types of cones give you the ability to perceive the full spectrum of color.

Photopigments are made of a protein called opsin and a molecule that’s sensitive to light. This molecule is known as 11-cis retinal. Different types of photopigments react to certain color wavelengths that they’re sensitive to, which results in your ability to perceive those colors.

Tetrachromats have a fourth type of cone featuring a photopigment that allows perception of more colors that aren’t on the typically visible spectrum. The spectrum is better known as ROY G. BIV (Red, Orange, Yellow, Green, Blue, Indigo, and Violet).

The existence of this extra photopigment may allow a tetrachromat to see more detail or variety within the visible spectrum. This is called the theory of tetrachromacy.

While trichromats can see about 1 million colors, tetrachromats may be able to see an incredible 100 million colors, according to Jay Neitz, PhD, an ophthalmology professor at the University of Washington, who has studied color vision extensively.
