I tried searching for this, but it matched a vast amount of unrelated topics.
Anyway, I’m trying to get back into lucid dreaming now, and one recurring problem I used to have was being lucid, but being totally unable to open my eyes. I can move around, touch things and hear things, but get little more than the odd squint at something before they close again. Any ideas on what causes this, how to avoid it or how to deal with it?
I too, would like to know others’ opinnion. Its really annoying! Espically if I know its a good dream. It usually happens in normal dreams for me. In lds what I do is will myself to see. Or say something meaningful to me that can make me see again. If it doesn’t work…keep trying! 
Remember, YOU are in control of your dreams…not the other way around. 
There’s already a member of this forum named lizard king, just letting you know.
There is no solution to your problem, you just have to practice more and learn to control them.
Yeah, that’s what annoys me the most, I’m usually good at controlling my LDs, it’s just this one thing that sometimes doesn’t work and ruins it.
