In message 15 I put it clear what I think about the subject of in-material entities perception. Nevertheless, as I think the term "subjective experience" is not being properly used along this thread, I would like to comment on it.
Any personal experience, of any kind, is subjective. According to Karl Popper, there are three worlds:
First world: the material world.
Second world (subjective): the perceptions produced by the material world in our minds.
Third world (objective): The theories, discussions, experiment descriptions, etc, rendered in books, papers, communications, etc.
Subjective experience, always may deceive you, also if it comes through your physical senses. As a prominent example, a man that has not gone over the polar circle, could be induced to think that the sun settles and rises every day, in all points of the earth.
