Focus is extremely important, I always keep that in my mind. And I always spend my WBTB time meditating. Trouble comes when I try to focus, but also to fall asleep.

But realizing I am dreaming is not my problem, I am quite good in that. Problem is my fear of LD. And you are right about the thing that every new experience scares me. That is true, and it is a good point, which needs to be considered: most likely during my WBTB this night.
