Let's see if I can help.

1) Yes, you must stay consciuos during the WILD process. This is essential.

2) For some, they feel as if they're in full control, and for others, it feels like they have little to no control at all. It depends on the person sometimes, but for most it's skill. For me, I am aware of what I do while lucid, but when I wake up, it goes away for a few minutes. It usually comes back to me when I recall the dreams I had that night. So I guess it depends, again, on the person.

Hope I helped! ^___^
