The problem with metaphysical theories such as these is they:
1. Fail to make a proper connection between reality and the metaphysical. They twist words to sound correct, but not experimentally stable (in fact, most have no experiments whatsoever). It explains what a hologram is and how it is made, which is proper. However, the paper then makes the sudden jump into saying "science is wrong and the universe is a hologram!" which is really off-putting.
2. Take what could be an interesting idea but warp it into nonsense. For example, this paper is a fascinating read until it starts claiming I can bend spoons with my mind if I just try hard enough. The author also believes dreams to be some proof that the mind can alter reality, when really they are evidence of the opposite.
