I think the out-of-body experience is always real insofar as being an experience that arises in spacial awareness like any other.

The real question is the nature of these experiences and we should always ask ourselves what evidence we have for the postulations we make---whether we take such phenomenon to be indicative of consciousness exiting the human body or merely an autoscopic hallucination generated by the 40Hz of gamma bandwidth of brain activity which Raduga et al call the 'phase state'.

Can OOBEs beget information that could not be known through physical/obvious means? Can we time travel or read people's minds in such state? What about predicting lottery numbers. Precognition? Interesting stuff.

The deck of cards experiment is something I have tried myself years ago after having a few experiences which many would jump the gun and call precognitive and telepathic. But I am a sceptic at heart and I always put to the test that urge in me to want something to be true. In fact I distrust it because the wish to be a superhero is a dream of desire.

The hidden card was randomly selected without being seen by anyone ...

I had an OOBE and did not see the card in the bedroom replica, but came across a woman wearing a crown embracing and kissing an ordinary man in the world beyond my dream abode.

I woke up to find that, in the real world, the hidden card was the queen of hearts.

I'd love to see more people try this at least 20 times to see how many 'hits', or apparent hits, they get, to see how results fly in the face of coincidence.
