There will always be stuff you cannot possibly duplicate in a lab...because it is not physical, measurable, or empirical...but it's still something that people really do experience. - if it can't be duplicated, and it isn't physical, measurable, or empirical, then it isn't data. People do all kinds of things inside their minds *which then become their experience* - doesn't make it any less a figment of their imagination.
Take the "voices" heard by schizophrenics and the odd manic-depressive - they are real *to the person experiencing them* but they are, nonetheless, figments of their imagination *in the real world*. If we didn't know what we do know from scientific exploration of brain and mind, we might think the people who hear the voice of god are actually hearing the voice of god.
Take the wonderful mystical experiences that lead "victims" of right-temporal lobe epilepsy to refuse treatment, as they'd rather have the wonderful mystical experience and fall down, drool and quiver, than not have the wonderful mystical experience and not fall down, drool nor quiver.
