Your snake is most likely looking for food or some sort of more favorable condition.
Things to make sure your snake has before worrying about the snakes mental health:

1. A proper hide. (My 6ft RTB just started rubbing the shit out of his nose on the screen for some reason and I found out he just wanted a more secure feeling hide even though he's never 'complained' before.
   
2. Prober temperature gradient. See where he likes to hang out in your tank and tweak the temp towards what you think he's looking for (I invested in a $14 mechanics temperature gun amazon so I can instantly read the temp of anything. Best purchase yet.
   
3. Different food choices. I've had a tree boa that did this in search for food every time she was hungry however would sometimes refuse rats despite having a visible appetite.. turns out she was a little racist and only liked eating white rats.. Sometimes snakes will only take a certain animal as prey, usually its mice though. Try a live pinky to stimulate the feeding response (and please never feed live prey unsupervised rats have been known to kill snakes; frozen/thawed strongly recommended if they will take it) Its important to have the thawed prey item warm to the touch. Dipping in warm chicken broth has also worked.
   
4. If you really cant get him to stop climbing around the trim, maybe give him a little perch to climb to. I use dollar store suction cups and thicker string as a 'jungle gym' for my baby RTB. It looks cool and they love it.
   
   Conclusion: I wouldn't (and didn't) like it either, but its actually not very dangerous for the snake unless he hits his head on something hard. They routinely fall from bushes and trees all the time in the wild. most likely if you satisfy his every need/desire, he will not go looking for better conditions.
   Hope this helped. You should also find a local small reptile shop (not a chain like ptsmart/petco etc.) you can call and ask questions, most of them are more than happy to give you advice, and theyve usually seen it all. Where I live there is a great place where the guy knows literally almost anything Off The Ark . If you're in the US, you could always give them a call, and just ask.
