So tonight I noticed Caesar came flying out of his warm hide and went crazy on the cage doors. He was breathing heavy and seemed scared. I let him sit for a few, then got him out and held him. He seemed scared for a minute, then when he smelled me and climbed on me a bit, he mellowed out and is now curled up sleeping on my arm with his face in my hand. Seemed like a bad dream? My beardie did this before when she was asleep. I picked her up and wrapped her in her blanket and she calmed down and went back to sleep. I wonder if reptiles can actually have bad dreams.
