That's very good.  You could say, "I see only...." and enumerate all
the other things in the visual field.  But it would be a mind-numbing

It seems to me that looking for an object, having it in mind, but not
perceiving it in the environment, is probably as close as we come to
having a viscereal, direct experience of a negation.

Note too that here we could understand this in terms of two mental
spaces -- one to hold the item sought, another to hold the current
perceived environment.

Were one given to evolutionary-style theorizing, one might suggest
that such situations were indeed the origin of the negative.
