Welcome to Glider Gossip.

If your glider just makes this sound for short periods of time it is fine. Mine make a similar noise, usually they are wiggling around in the pouch at the same time. I feel it is similar to a dog when dreaming may make running motions and perhaps even a muffled barking noise.

If your glider is making this noise for extended periods of time - a vet visit would be in order to check him out and make sure he is healthy.
