I have read comments from people who have brought them in to overwinter... It is do-able but probably best put in a place that remains cool (above freezing, probably preferably above 40° F), with reduced watering. The comments mention potential insect issues too. Under those conditions, it'll probably go through a brief period of dormancy (and you may want to let them have it) - even if you had it in a sunny cool spot. If you want blooms indoors, you will most likely need some pretty high-intensity light or maybe a sun room. Also you'd need to watch out for low indoor humidity as the hot dry air from heaters in winter can be a death knell for overwintering plants (crispy leaves, white flies, spider mites, etc). In that case, you would want to run a humdifier nearby and/or place the plant on a pebble tray where it can get some moisture in the air around it.
