Hi! Ok so, its actually quite simple. Brumation is a semi-hibernation that bearded dragons go through with temperature changes, or simply what time of year it is. If you have a hide available, they will often just go hide in it, some of them are semi-awake and will come out to eat every now and then, but not all of them do. So it is best to provide some food in case your beardie wants to eat, but they usually survive off their "fat-pads" at the base of their tail and on their head. From what I've read, it seems preferable to dim your lights, or turn them off and turn them on once you see your beardie moving and waking up again. Hope this helps!
