My Oscar snores lightly sometimes. My Maggie, however, takes things to a different level with her dream-talking. She loudly moans and cries and whines and barks and it tends to worry visitors, but she has always done it (she's very "talky" anyway when awake, and through whines and rfffs and growly moans rather than barks). My late Airedale, Monty, used to do what in Airedale Terrier circles is called The Midnight Howl. This isn't just a normal dog howl, but rather one done by the dog while sleeping, and is a sound that builds up almost exactly like an air-raid siren, until the neighbours are switching on their lights wondering what that horrific, Lovecraftian wail is, and how long their souls are for this world (we did not have any souls left after the first incident from Monty, them having been scared from us to hide in the darkest corners of the cosmos). As mentioned, the source is still asleep, even while his cries shake your foundations (literal and metaphorical). It's times like that that you can appreciate the gentle, lulling tones of a simple snore.
