If you ever get the chance to experience a mind altering drug eg mescaline psilocybin or LSD, you become acutely aware for the first time that we are actually a 4D reconstruct. Just like a guy sitting in the control seat somewhere in our brains watching the big video in front of us hearing our inbuilt quadraphonic sound system with tactile input, this becomes obvious as the drug temporarily changes our perceptions and the image reconstructed has brighter colors the edges of things take on magical, mystical patterns and moving shapes. This is quite mind opening as we realize, after filtering out billions of processes leaving use to deal with the critical top thousand or so per second, that the reality we accept as fact ie the Id is actually a accurate brilliantly realistic FILTERED reconstruct of our environment. So I agree our perceptions are like a 4D hologram.
BTW you dont need drugs, people near starvation, dying, severe dehydration can induce similar states. My point is very few people actually get to see this with current legal status of the substances necessary.
