To ask of any experience, who is experiencing this? is to beg the question of consciousness as necessarily formed according to the subject-object duality. This is far from self evident and appears to be an artifact of waking consciousness as a serial processing variant of intelligence. It's possible that qualia, the sense that there are obviously such things, and with them the entire 'hard-problem' is also an artifact of the same kind. The cure is to reincorporate serial mind into parallel mind and then determine if any such tautological self or subject still arises.
