Before (Materialist View):
A rock is real because it is made of atoms. A dream is not real because it is made of neurons firing. Reality is determined by "stuff."

After (RDD Pattern Applied):
A rock is "High-Gravity Reality." Its distinction pattern has recurred for eons ($t\to \mathrm{\infty }$) and requires immense energy to disrupt. It has deep Recursive Inertia.

A dream is "Low-Gravity Reality." It is a valid distinction pattern while it lasts ($E=1$), but it lacks Gravity. Upon the next major recursive update (waking up), its coherence collapses into entropy. It is "real" for a moment, but not "persistent."

Conclusion: Reality is a gradient of persistence, not a binary switch.

• The Container Fallacy: Believing Reality is a "box" (Spacetime) that things are put inside. (Correction: Spacetime is a distinction generated by the engine).
• The Solipsism Trap: Believing that because Reality is perspective-dependent, it is "just in your head." (Correction: Gravity ensures that shared, high-persistence distinctions exist independently of any single ego).
• The Material Bias: Assuming that only physical matter counts as real. (Correction: A "Law of Mathematics" is more real than a chair, because it has higher recursive stability).

• Is a hallucination real in RDD?
  Yes, but it is unstable. It exists as a distinction ($\mathcal{D}$) with a Perspective ($P$), but it fails the test of Interaction/Gravity ($G$) and dissolves quickly.
• Does Reality exist without an Observer?
  No. Reality requires a Perspective to carve it. However, "Observer" $\ne$ "Human." An electron is a perspective that maintains the reality of an atom.
• Can Reality change?
  Yes. Since Reality is just the current state of Recursion, if you change the distinctions being fed back into the loop (e.g., through technology or consciousness shift), you change the physical structure of Reality.
