Yes, this is a possibility. The considerations you have are leading to the core of how our reality in itself is established. For this kind of questions we will principally never get an answer which can be "prooved" in a usual, material-physical way, as all those "proofs" would be in themselves of the nature of reality we want to have a proof for.
    So, what is left is to get an overview of what possibilities there are; and different people will allow different things to be called a "possibility". When we consider informations we've gathered during a retrieval experience to be actually gained by telepathy from still living people, we have as well to believe in the consequences of that: That is telepathy, and although a somewhat common term, the consequences are immense. No less the consequences when we consider the retrieval informations would stem from a kind of universal database; we then had virtually access to all informations we look for, and maybe we actually have access to this database all the time, constitueing our reality to a large degree. Or you simply go with the possibility that it's a deceased person, now nonphysical, who gave you the infos. What seems more likely to you? The decision you make is indicating what belief system you have; but watch out that your belief system is not containing contradictions, or it would crash sooner or later and you have to rebuild it. Well, those things happen.

I've found that spiritual experiences can play out in a way that are just as substantial as this physical World. Is our experience of this physical World the result of mind reading?

Hi Ronny,

I hope you will continue reading the rest of Bruce's books.  I'm assuming you will, since you are here posting.  You probably have enough interest that you'll continue with the rest of Bruce's story.  That's what his books are, his story to tell.  It's a guideline for people to follow who want to discover for themselves what is true and what they want to believe.  If Bruce only had one experience in his life to go on, then he himself would not likely believe what he believes now and teaches.  It took many experiences to learn from before his belief system became what it is.  And that's what we all have to go through individually.    

The thing about verifyable information is, you may not always be able to find proof that is satisfactory to other people, and that's ok.  You may have an experience that doesn't give you any solid, verifyable real-world proof at all, and that's ok too.  As long as you have some proof in one or some of your experiences, enough that it changes or opens up your belief system enough that you can have experiences that prove to YOU that what you are experiencing is real, then that's all that matters.  You will learn to trust your own awareness.  That's why it is important for each individual to seek out and verify (to his own satisfaction) his own experiences.  The more you learn to trust your own conscious awareness, the farther you will progress in your skills and experiences.  

Proof to the individual is what it takes to open up your own perception and unblock your beliefs.  So when Bruce talks about his experiences and tells his story, it is because he has already gotten to the point where he fully believes and trusts his own perception and experiences.  And you will find yourself at that point one day as well, if you continue to search and learn from your experiences.  

If you notice, Bruce's first book really shows how he struggled believing if any of this was real or not.  That demonstration in his first book really made him seem very credible in what he was writing about.  And then as his books progress, he does away with that and just dives right into telling it like it is...just telling his experiences as if he couldn't care less if anyone believed them or not.  Because the truth was, at that point HE believed in them and that was all that mattered.  I think that's why he teaches us to find our own truth from our own experiences.  His sharing his own stories is just a guideline for anyone who is interested in the same thing to follow his example and have their own direct experience and come up with their own conclusions.
