I would try NOT dwelling on it. You have two eyes I presume. It would fit that the dream you would as well. I beleive that the more someone dwells on a problem that they are trying to fix the more it manifests. Just try and tell yourself that you do have two eyes. It is all about confidence the way I see it.

It sounds like you have good control though most of the time. HAving four out of five clear dreams is alot more than I can say for myself. (Heck, I rarely have them anyway.) So good luck with that!
