to be honest, i don't dream of electric perl sheep. (blade runner is *such* a great movie, btw.) not yet, anyway. i do find myself thinking aloud in c++ or pascal frequently, much to the chagrin of a coworker of mine. :)
of course, my background in those two languages is much stronger than my background in perl. i hope to be perl-ific enough in perl that it comes to me as a second nature. well, maybe that's setting my sights too high, but you get the point.
coincidentally, while the subject of dreaming is up, i have a dream *completely* in french probably once a month or so. which is very strange, but i LOVE it. it lets me know i'm that much closer to fluency. :)
