"Lightning of possible storms"

Greetings: I have this vague feeling, which is driving me crazy, that
somewhere in one of Foucault's texts (interviews?) there is a line that
goes something like "I dream of the lightning of possible storms." Does
anyone know if this is, in fact, Foucault, or if not, who it is, and in
either case, where it's from?

Thanks muchly,
Matthew
