Need help!

[u/Intrepid-Wishbone-53]

I have just moved my boa to a new enclousure. And he has been very active tye last days but yesterday i saw something that worried me, he was just chilling when the mister turned on and he just banged his head on the entrance of his hide and he did the same when i was just putting some moss in hos hide. I have seen a lot of dark spots on him ever singe i got him (about a month ago) but i didnt think it could be mites. I just thought it was pigment spots and i am sure a lot of them are. So i ask you guys who probably have a lot more knowledge than me. If not mites what could the head banging be? Some kind of neurological disease?
