There everywhere, but I've always been partial to the dodecahedron, ?

Well you ought to doubt everything really, including patterns, since your brain is less a computer than a pattern matching engine (generally optimized to search for pattern discrepancies in an over-eager fasion). Or put another way your brain is prone to seeing patterns that don't exist, but that you want or need to see. This is called "confirmation bias". You are also generally biased to assume agency where it doesn't exist, as this is (or used to be) a survival advantage. This is called "agency inference". These two together have the nasty side effect of encouraging religion.

Discerning and verifying patterns is a wonderful human capability though, rightly used.
