Some Bearded Dragons will go into a deep sleep, and won’t wake up at all, for weeks on end, until its time for them to wake up and remain awake. Others will wake up periodically, either on their own, or if their owners wake them, and then go back to sleep again. Still others may just take long naps. And others may not actually go into a deep sleep at all, but will just refuse to eat anything. It all depends on each individual Beardie, and what his instincts tell him to do. It may take you a year or two to discover what is normal for your particular beardie, so you know what to expect from him.
