Well it is normal if your beardie is old enough to brumate and all of your husbandry is correct.
If you would like to answer a few questions, we can try and help you figure out if it is indeed symptoms of brumation or something else.
How old is your beardie?
What brand and type UVB are you using?
How old is your
UVB bulb?
How close can your dragon get to the UVB?
Do you use a separate basking bulb? What kind and what is the wattage? Is it a white or colored bulb?
What are the basking temps?
What is the cool side temp?
Do you take the temps with a stick on thermometer, a digital thermometer with a wire and a probe end or a temp gun?
Do you use vitamin or calcium supplements? How many days a week do you use each of them?
Is your dragon having regular bowel movements (poops)?
Have you gotten a vet check and fecal done?
