I had that problem too. Ones times it felt like my eyes were glued shut and that was weird and then I had a false awakening. I don't think about blinking because in my dreams if I'm aware I'm blinking my eyes glue shut again. Willing away eyes problems might work. I think if you have eye problems in any dreams try putting on glasses. Sometimes for me it clears up my vision if it's blurry or whatever, maybe it will stop your eyes itching?
