I love it when I run into a bunch of new ideas, all at once. A rich seam of the imagination, as it were.
It's not like coming up with new ideas. They're not new, I've just never noticed them before. Or, rather, I've found a new way of organizing them, that grants them some meaning I've never realized they had. It produces a sort of ripple effect, because that meaning allows me to put other ideas together in new ways, and that produces new meanings.
It opens a new corner of the matrix. That's how I think of my mind, when I'm in the mood. A collection of data, connected by links that are themselves data. The whole structure is prone to shifts of meaning when new ideas are added to it.
