Lol maybe he had a bad dream. My beardie has woken up in a frenzy before and shot out of her little blanket like a bullet, ran across the cage and stood there like in shock. I picked her up and wrapped her back up and held her for about 30 mins and she fell back asleep lol. Only ever happened once in 4 years.
Well at least he is back to normal so I guess just chalk it up as a snake being a snake lol.
