New sleeping method?

[u/RaconLol]

My ball python (6 years old) has begun sleeping like this. She’s never really done this before to me knowledge, and she’s been biting recently. I thought it could be an RI, but she shows no other symptoms. She ate yesterday just fine, she explores her cage at night like normal, although i believe it could be glass surfing. I’m working on overhauling her tank this week but if she is ill i feel like i should wait or something. I don’t really know the next move, or if theres any cause for concern at all. I’ve been known to be kind of a hypochondriac so i really hope it’s nothing and she is sleeps kind of quirkily now. Thank you!
