For someone deep into science including neuroscience, I'll attempt to be brief without writing a book or confusing most members. Humans usually end up spouting nonsense when trying to use language to describe science things they don't have adequate knowledge to reasonably understand.
Earth creature animals evolved brains that create internal electromagnetic field (EMF) perceptual representations of their real external physical world in ways that allow their brain's thinking executive control "pilot" to operate successfully to their advantage in their world. Most people probably think that when they as in that mentioned EMF, see something, that they are directly perceiving their actual eye neural rod/cone neural sensors. Or when one feels something with touch sense neurons say in a finger tip that their EMF is actually directly perceiving that part of their nervous system in their finger tip. 3-dimensionally it sure feels that way. Same idea for all other senses.
But such are illusions because animal brains have a deeper structure our senses feed into after various degrees of higher processing that is the seat of what our EMF are actually directly aware of. That is why we don't confusingly see two independent visuals using our two eyes. Instead, the brain combines the two sense streams into a more creature usable deeper internal functional single view for the EMF that is the true seat of awareness. The validity of that interpretation becomes obvious when one considers the cortical homunculus.
https://en.wikipedia.org/wiki/Cortical_homunculus
A cortical homunculus (from Latin homunculus 'little man, miniature human) is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the human brain dedicated to processing motor functions, or sensory functions, for different parts of the body. Nerve fibres—conducting somatosensory information from all over the body—terminate in various areas of the parietal lobe in the cerebral cortex, forming a representational map of the body.
There is a long list of optical illusions that further prove that what our brains perceive are no straight representation of our incoming senses. Sense neurons only provide sense inputs that a creature can use. Accordingly our touch senses didn't evolve to levels of say feeling constant molecular vibrations. Nor do our human nose olfactory senses perceive fragrances at fine levels of other animals like your pet Fido, because there was no advantage for humans. Fido's awareness of some chemical may be closer to the truth but again is merely a wider range of an immense physical range. Fido can't smell the difference between of siliceous precious gems rubies versus garnets because that would have no creaturely use.
