My hedgie made a noise I haven't heard before

I've had my hedgehog Pin for 9/10 months now, and just now while in his lil sleeping hut he made this squak sort of noise that was way louder than his usual huffs or growls or anything. It terrified me. But he's not showing any signs of distress or health issues that I can tell? He seems perfectly content like usual now.

Can hedgehogs dream or get scared or something? He was just in his hut like usual and nothing new had happened to cause the noise?

It's possible it was actually a noise outside my room since his cage is along the same wall as my door, and I just panicked. But I figured I'd ask if that's something others have experienced?

What an intro to a new thread, let me know if I need to add tags or change anything abt this <3
