Robert Monroe in one of the excerpts from OBE experiences gave a suggestion that perceiving people, objects, beings etc. could be a projection. This was the case e.g. with one man, the explorer who met in this state a strange female being, and they had communication issues (she didn't quite know what is matter for instance), and they both couldn't say whether they perceived true form of themselves, or each of them perceived just a projection. Another similar example is for people-believers in their after-life experiencing the version of paradise in accord with their religious beliefs. Examples are numerous, but the general idea is clear: our mind is the ultimate observer, but the question about the precision of the form perceived is still open.

What do you think - is everything perceived in OBE, LD, and similar states of consciousness, ultimatately just a projection?
