Generally in a dream state like that, I find that what you believe & intend will happen will happen whether it makes sense or not. You knew you were dreaming and that the wall was immaterial, but you didn’t accept it in time. That’s one of the basic skills involved in lucid dreaming, really, influencing the dream by thinking “Oh, of course this is what will happen next” without pushing it too hard and waking yourself up (or getting stuck in sleep paralysis, in my case).

If you have nightmares, lucid dreaming techniques can be helpful for overcoming them. People often make stressful dreams worse on themselves by worrying “What if the monster catches up to me?” or “What if my weapon doesn’t do anything to it?”—you’ve got to follow it up with “Nah, I think it’s friendly and I can ride it” or “Of course my attack will work”.
