Can the natural human eye "really" see ghosts?

Human Magneto-reception and Paranormal or Etheric Perception

PARANORMAL 

There was a story about magneto-reception I found intriguing.  Magneto-reception is the ability to detect magnetic fields.  Many animals are believed to have this sense and use it for navigating the earth’s magnetic field.  For humanity, it seems like a lost ability.

A recent study in Nature Communications discussed a protein in the human eye that seemed to have magnetic sensing properties.  When this human protein was inserted into fruit flies, they became sensitive to magnetic fields and were able to detect them.

Here is the story:  Human eye protein senses Earth’s magnetism
I’ll offer some speculation.  Could human magneto-reception help explain paranormal perception?  There are countless stories of human beings seeing normally invisible spirits, ghosts, angels, and faeries.  Sometimes, rarely, someone will have a vision of something anomalous that appears very real. These visions have been regarded the result of an overactive imagination.

What would happen if, on occasion, our retina briefly perceived the electromagnetic world?  We might see a blurry image of light and try to make sense of it.  We might even call it a ghost.
A theory about ghosts and spirits suggest they interact with the physical world by manipulating electromagnetism.  It has been suggested much of paranormal activity could be explained by magnetic fields.  Cold spots in hauntings are said to be spirits drawing energy from the surroundings to manifest them.

Can we train to see invisible or magnetic fields?  There is an exercise anyone can use to develop etheric (electromagnetic?) sight.  In a darkened room, hold your fingertips as close together as possible without actually touching them.  Focus your body’s energy towards the tips of your fingers.  Then look at the fingertips indirectly, out of the corner of your eye using your peripheral vision. Slowly draw your fingers apart.

You might see a faint astral light, almost like smoke, streaming and swirling between the fingertips.  I have seen this myself.  Someone who suggested they had psychic abilities once demonstrated this to me. From the edge of my eye I saw something like a tiny, dimly lit vapor interacting between their fingertips. Was I experiencing magnetoreception?
