"From dreams recollected..." What It Is & Where It's From: A Nonsense Rhyme

From dreams recollected. From fancies confected.
(It's nothing Bill Veeck did, nor reckless Glenn Beck did.)
Debuts unsuspected. D'ja vus resurrected.
(It's nowt Bela Fleck did nor aught Chiang Kai Shek did.) 

Affected. Reflected. Ex more inspected.
Finessed a la Greque, though by Shrek undetected.
(It's nothing no Czech nor no dead Zapotec did,
nor nowt Lech Walesa nor Gregory Peck did.)

Its lemmas? Dissected. Heck! Hypercorrected.
(Nowt Halo nor Breck nor no Antarctic trek did.)
It's ever respected. It's left disinfected.
(Nor -- just for effect -- is it something Cal Tech did.)

Perfection? Neglected when interconnected.
Erected in texts. Into tracts architected.
It's schtick Prilosec, plus an old tarot deck, did...
what "Nescio autem non volo noscito"* did.
     * In Latin, very roughly, "I dunno...an' I don' wanna know."
