I picked up this book because I am at a non-stop search for the universal truth. The title is what caught my eye. What if everything we know to exist is just a hologram that our mind projects and sees as the world. If you are open-minded, free thinking and just generally want something interesting to think about this is a good read. It's not always easy to follow, especially if you know nothing at all about topics like this, but you will understand what is written. It tries to explain why we have dreams, premonitions, etc with the holographic theory. If you are totally dedicated to religion you may think this book is explaining away God. Nothing could be further from the truth. I believe strongly in God, but my beliefs are from proof such as this. Evidence based beliefs are the only way you can prove existence of a higher power and this is one book of many that tries to do that.
