Yeah, I didn't really look into those sources too much to see if they were reliable. But they both certainly hold a rong of truth. The problem is that this isn't guarantee.

And about the childhood memories, zoth, perhaps living through some memories, it can bring it to conscious mind. Like, 'ah, i remember that now!'

I just thought of this. I was thinking, what if you could read in a LD? Then, I thought you could find your 'this is my subconscious book', and read through it. It could be good since it would tell you things you wouldn't think to ask. But, who wants to read in a Ld? And even if you did, couldn't that make your dream fall apart, and how much reading could you even get done? Instead, you could jump inside it, and see what is there? Though, you could just end up where you want. But maybe if you want to where 'the book wants you too?' IDK, it could be worth a try.
