What happens when you become lucid and then look in a mirror?

The other night I caught my reflection while lucid dreaming nd my face looked normal EXCEPT for two very strange things... 1) I only had three teeth! 2) My eyes which are all weird - my pupil was in the shape of a crescent moon, and when I looked away and back again, it got worse... My eyeballs were all shrunken and they really hurt when I looked at them.

What's going on with lucid dream mirrors? I always seem to have funny eyes and teeth when I look in them.... is it just me?
