I just started working on LD this week....have not had one yet. In all my dreams in the past it seems like I can really only see or notice my immediate surroundings, outside of that, it just seems like nothingness or I don't even notice there is anything there. That is until last night, in my dream I could see a huge set of doors that were something like 200 feet tall and about a 1/4 mile away. I also was in a large abandon parking garage and I could see all the way to both ends. For me, I think in the past I just went along with the dream and recently I am working on being aware of my dreams and that is helping me to notice things. I have notice this too in faces. I have never been able to notice faces in dream, my DCs had faces, I just never seemed to look at them or notice them but last night in my dream when I was in the abandoned parking garage, there was a toddler and I clearly say their face, I even noticed that it had a black eye. I can only speak for myself but it seems like as I work on thinking about having more detailed dreams and noticing more detail in my IWL I notice these things in my dreams.

Good luck on working on noticing the details of your dreams, I would really like to hear what you find.
