Yes, on a night dive. I was following another diver (my sister) too closely and she stopped unexpectedly and kicked the mask of my face and reg out of my mouth. This was shortly after my OW cert. I recovered as I was trained to do and all was well. Only my buddy knew what happened until we got back to the boat.
Totally my fault, and a noob mistake, but we were all noobs once.
