Your brain is incapable of inventing something as nuanced and complex as the world. You are likely incapable of understanding the most basic principles that define existence, such as biochemistry, cosmology, and geology. And yet, these remain consistent?
Furthermore, it is unlikely that you are a professional musician, cinematographer, or writer, so where does art come from? Your own mind? Don't be so egotistical.
I find that the delusion of the holographic world is rooted in narcissism and a failure to appreciate The complexity of the universe.
I find the comments here generally miss the point. They seem to entertain this delusional line of thought. You simply are incapable of making this all up.
I call this, self loathing. But, in all seriousness, if you are a critically minded person, it stands to reason that you'd see flaws in others but even more so in yourself, whom you know more intimately.
