Interesting thread - I do believe that our reality isn't really real. It's mostly based on thoughts, conditioning, our limited senses, codes, etc. It's amazing how much we may think something is real, only to find out hours, days, years, decades, or centuries later that it isn't so.
If we think it's real, then it real to us, but on a universal or dimensional level it's a different story.
Speaking of David Bohm, I recall that he and a favorite philosophers of mine, J. Krishnamurti, co-authored a book (I have to find it) about this same subject - Thoughts. Needless to say it's a very profound book. Now that you stirred up my thought process, I have to find that book.
Thanks - LL :)
