my boy has started occasionally making these sounds when he's asleep. it ONLY happens when he's asleep, and it doesn't stay like this super consistently (it took me a long while before i caught it on video), but he's never been so noisy, so it's making me a little worried </3 he doesn't seem bothered or uncomfortable when he wakes up, and he hasn't had any change in behavior/rabbit indicators of discomfort, so it doesn't seem to indicate he has a lack of oxygen or some other underlying ailment (and again it only happens when he's sleeping), but i just wanted to ask my fellow bunny owners.
p.s. he does have a big fat silly nose, so he has been known to make some silly sounds every once in a while, but never anything abnormal. i'm not sure if that context will help at all.
