Can't see

Date: 1/24/2017

I have reoccurring dreams where there is something very important that I must see but I am unable to open my eyes. And if I can open them, it is very little and not enough to actually see anything at all. The subject of the dream is always different, and sometimes it's a nightmare type, leaving feelings of anxiety and such. But other times it's mostly just frustrating. Does anyone else have dreams like this or an explanation as to why it happens so often??
