Is it odd that my collared likes to sleep like this?

I recently put back this background I made for her into her tank after being out of it for months and months, and she climbs the walls and loves it and I think maybe a little too much? She found a spot that has a big enough gap for her to lay on one of the rock formations near the top and go to sleep. She has a rock hide that she used to sleep under when the background wasn't there, but now she likes to sleep up here. Does she enjoy the feeling of hanging? Or does she like to sleep up high? It's weird.
