Parabolic Mirrors are not actually mirrors, but they're not not mirrors. They're more like " mirrors that don't really reflect, but kind of, sort of, maybe reflect, but only if you're in stealth mode, which you probably aren't, because you're not even here."
Parabolic Reflection Symmetry (PRS) - Where the mirror image of you is only slightly distorted, like your self-esteem after a few too many selfies.
No Reflection at All (NRA) - Where the mirror just shows a solid black rectangle, like your soul after a few too many late-night scrolls through social media.
