They don't snore but they can make a sort of chirping grating noise in their sleep sometimes. It may be because it is so warm and she is getting a bit hot in there. Keep her shaded and in a cool room and chill a plate in the fridge and pop that in her cage to give her a cool area to lie on.
Check her for wheezy or clicky breathing though as they can get human colds and chest infections which are quite serious in hammies. I hope she is OK though.
