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.
