Another thing to think about is often when we start out lucid dreaming, we see through binoculars, without the zoom. When you see, as in right now, you see the monitor, whats directly behind the monitor and around it, the desk maybe, your arms, and stuff right beside you.

In dreams, we only see exactly what we are looking at, and we just get hints of what is around us (the location and colour, maybe a few objects). Until we look around do we notice things and build up awareness. Next time, try slowly turning around and seeing everything, don't just try to clear up one little thing. Thats what I did, and it was a short lived LD.
