I need help please! (popping sounds, weird breathing)

[MushLover123]

This is really weird but ever night my bearded dragons makes weird popping sounds and seems to breathe weird I’m not really sure what’s going on. I know most of you are typing RI RI RI go take him to the doctor. That’s the issue I did! It only happens at night and during the day he’s as healthy as ever! Even the vet didn’t see anything wrong with him. Any ideas? It gets kinda cold at night for her since I live in the basement and I bought her a heating lamp but it doesn’t seem to have stopped it. It’s weird. Please help!

As long as the vet thinks it's okay and he is healthy I wouldn't be worried.
