Welcome to the forum

1) I don't know a lot about WILDing, but I do know your body will always go into SP when you're sleeping. Whether or not you notice it happening every time you WILD, I don't know. I personally do.

2) I first started having LDs as a kid, and logic told me that since it's in my head I should be able to control them.

3) Yeah I have a natural ability to remember my dreams pretty well without a DJ. To improve your recall you can start up a dream journal, it also helps you spot possible dream signs.
