In this situation and to solve this particular riddle, it is important to look at what all of the things happening are telling us. Peeling paint, missing curtains, and boiling water all point to a problem like a fire. The first part of the riddle, waking up in the morning, isn't very meaningful as fires can happen any time of the day.
However, symptoms like peeling paint, missing curtains that have likely been burned, and boiling water, are all due to one common problem of the house being on fire. In this case, none of the individual symptoms should be dealt with first, but rather the answer is to leave the house immediately.
