What is quantifiable are the symbols. What isn't quantifiable are the zones between the symbols, unless there are many symbols present that form spaces.
There are partial symbols, i.e. a gesture of an animal is present but not the form of the animal.
Reality stays more abstract with partial symbology.
What is known about the symbol gives reality meaning.
Speaking of visions as symbols separates the meaning from the visual experience.
The person who doesn't see the symbol as the reality has not been exposed to reality which is somewhat hard to ascertain.
When, in dreams for example, there are just collages of things, it is hard to say that it is more than a collage. But if I recognize symbology, it allows me to see every part of the picture.
Symbols are more for the artist than the scientist who simply wants to verify what happens in reality. While transcendent of verification of meaning is reality "filler", yet it attains to meaning only if it is seen as symbol.
The filler is more abstract because logic only exists here if we consciously give something meaning. Otherwise a huff of a dog, for example, is merely a passing image.
Since concrete objects already have existential meaning, they cannot constitute as filler.
Visions, because they only partially exist, calls into question existence itself.
In filler reality, it becomes participatory as to giving reality meaning or just enjoying the visions.
What separates this filler world from normal mind is that meaning is no longer the key to reality.
Simply experiencing the visuals explain reality in an easy way.
Meaning almost ruins the mode of experience.
