my bearded dragon always acts a little weird when his lights go out. his lights come on between 6 and 8 and go off between 8:30 and 9. when his lights go off at night i also go to bed so there is zero light in my room except for the screens on my devices. i can always hear him moving around after all the lights are out for around maybe 10 or 20 minutes. it sounds like hes scratching at his walls. i never turn my lights on to check because he always settles down and from what i can tell sleeps fine the rest of the night. the area he sleeps at is in the back corner so im not sure if its him trying to get back there or something else. how good is a dragons vision at night? should i try putting him in the spot he sleeps when i turn the lights out to see if it makes a difference?
