Bearded dragon brumating again?

[zazo]

My bearded dragon has been displaying unusual behavior lately. After a three-month brumation period that concluded about a month ago, today she dug a burrow and spent the entire day sleeping in it. Despite maintaining proper UVB and temperature levels, with an Arcadia T5 and basking spot temperatures ranging from 38-42 degrees Celsius, she hasn't been basking as usual.

While she appears healthy, maintaining a regular eating and bathroom schedule, I am concerned about this change in behavior. Could there be a possibility of brumating twice a year? Any insights would be greatly appreciated.

I'm not sure myself, mine brumate every year but when they're done they usually just behave normally. Well, one did go back to sleep for an extra 2-3 weeks last year actually. She might come back out soon. Other than that I don't know.
