Hi dream,
I also have astigmatism in both eyes and I get where your coming from with how it's real clear in lucids to how it's slightly blurry in RL, but that blurry ness isn't a lot is it, not enough so you can't see good. Anyway to the point lol...sounds to me that the fear is stopping you, but on th other hand I myself believe OBE are lucid dreams, so when you have an OBE again believe that you can change it, believe that behind a door etc will be a beautiful beach or wherever you want to go, you don't have to be stuck in your room when your in your dream body please get it out of your head that it's something evil stopping you as his will hinder your progress, if you need to, imagine yourself being covered from head to toe in a beautiful bubble of light as you lie down to go to sleep, and say "only my guides can help me and connect with me" this will help a lot. Hope this helps, let me know how you get on please
