Without turning on the oven at all, place a kitchen towel on the bowl in which the dough sits, and place it in the oven (a warm place - assumes you have a 30-40 yr old gas pilot lit oven), alternatively, if you have an electric blanket make a nest for your bowl, put the blanket on the lowest setting, towel over the dough bowl and wait. Sometimes the dough looks dead from bad yeast, but given time and a warm spot will have a better chance to revive and rise but it may take a long time even in the warm spots (check in an hour).
I usually put hand-knead in the furnace closet with the water heater. It's nice and warm.
In that warm spot, I'd give up after 4 hours before pronouncing it deceased.
I dunno, last idea: make a dough 'mouth' put a little milk and sugar in the 'mouth', re-knead after feeding it.
