I had some spiritual experiences, see http://transcendentalists.org that dispute all superstitious religious beliefs for which I sought Dr. Pim van Lommel's (cardiologist) advise. Your opinion thereof would be appreciated.

He stated: Dear Kurt Kawohl, You can call consciousness outside the brain "spirit", if you like. But this can be confusing, because not everybody has the same ideas about what exactly "spirit" should be. And there are several "levels" of consciousness, waking consciousness, dreaming consciousness, "subconsciousness", collective human consciousness, morphogenetic consciousness, higher cosnciousness, Cosmic consciousness, Divine consciousness. All these levels of consciousness are interconnected, and available, also during our life in our body.

I agree with you that also deep mental stress can facilitate the access to other levels or other aspects of our consciousness, but also NDE, meditation, regression therapy, isolation, depression, terminal illness and other circumstances can facilitate this effect.

This phase-space is a higher dimensional space, presumably not just the fourth dimension, according to Quantum Mechanics. Induced experiences are never the same as a NDE, sometimes several elements can be experienced, like flashes of the past, a feeling of not being in the body, or a period of unconsciousness, but aspects like a life-review, or transformation after the experience are hardly mentioned after induced experiences. All ND-expeirences are personal experiences, where finding words for it is very difficult, and cultural, demographic and religious factors play a role in this. So I have never heard a similar experience ever.
