Can't see in my lucid dreams?

I've done a dild and a delid where this happens and I don't know what I'm doing wrong. I'll be getting out of bed or walking around and than I just can't see what's happening. I can feel everything and move around like before but just can't see. It's like my eyes are closed or my vision pauses. I did stabilizing techniques and it helped at first but it just happened again later in the dream and causes it to fade. What can I do it prevent this in the future? Also if you want to see what's going wrong I have these dreams in my online dream journal.

As William Buhlman recommends - ground yourself, calm and focused, and command loudly, "VISION NOW" and "CLARITY NOW". Calmly imagine the scene unfolding and it will open in front of your eyes.

I've used that technique before but not in this situation. It's a good idea I'll have to try it next time I run into this problem. Thanks!
