That sounds troublesome, or harbingersome. For one thing, the excessive complexity suggests that someone invented it -- and in somewhat of a hurry -- with the intent of giving it to you. Perhaps you did yourself? That often happens to Mentador magi.
But you could probably figure out something about how or at least when you got it. It would take a substantial chunk of time and cley to graft, at least if it were done quickly. Look over your cley log, and see what's missing. (You do record every cley you use, the way that all the books on professional magery recommend? ... Me neither. Every couple of decades I pick up a cley log book, but never get past the first page.)
Or perhaps you have constructed a splinter consciousness in the back of your psyche, and it's eagerly doing spell research. I do something along those lines myself, though of course with the far safer and less repugnant art of Tempador.
Good luck, in any case.
