Riddle Me This

Riddle me this, What exists? Does a fairy tale? Does a myth? What about the number 6? Does stiff really, mean stiff? And if, It doesn't, then what exactly does that make what? Who discovered another species of stuff that we make up? A feeling, an energy, A new unknown frenemy. A quantity, commodity, an unknown entity. Top secret hidden agendas, undercover intentions lead, You to the brink of destruction trying to erase the image of all things that you've seen. Merrily, merrily, merrily, Life is but to dream, momentarily. The illusion of a playwright, All commencing in a ceremony.
