Is my bearded dragon going into brumation?

[brooklyn2301]

I have a 1 year old bearded dragon, and lately she has been very sleepy. Every time I come upstairs she's asleep but if I move towards her cage, she wakes up. She refused to eat yesterday so I really hope she is going into brumation, and she's not sick. Should I turn my lights off and put a blanket over the tank so she can get some sleep? I'm worried about doing this in case she's not brumating. This is my first time dealing with this so I'm kinda nervous.
*edit*- I am giving her a bath right now and she's a darker color than normal. Does this mean anything?

It's possible. I would leave your lights on the regular schedule. Take her out once a week or so and weigh her. Then offer some water via drips on her nose so she can have a drink if she wants. I'd leave a salad in the tank too so she can have something to eat if she wants but their metabolism slows down to the point where they are rarely hungry. If her weight is staying pretty stable it's likely brumation and she is OK.
