In Which There is Learning for All

I love the routine we've settled into since Lucas and Joel got here Friday. I went ahead and took a few days off of both jobs, calling it a family emergency. I think my bosses were so gobsmacked by the idea that I have family that they didn't question why two little British boys qualified.

So, this is the first vacation I've had in years. And I'm spending it frantically trying to do large amounts of research and teach everything I can to Lucas and Joel. Strangely, I'm not only fine with that, I'm really enjoying this. It's been really peaceful. Even with that strange shared dream that apparently I had with Morningstar and AmalgationSage. Uhm. I don't even know.

Right. But the important bits. For those of you with Holmes level deduction skills, this should be obvious. For the rest of you, let me lay out what I've been doing. From what I've read, there are a lot of conflicting theories on what to do if Tall, Dark, and Faceless has already taken over your mind.
Ideally, in the long term, I hope to find something conclusive on the matter, so that I can help those who need it. This is not my current goal, however. My current goal is to help all the runners who are suffering Slendy effects, becoming sleepers or getting turned into proxies or honestly just losing time or going crazy.
So, after doing a lot of research and borrowing heavily from Hakurei Ryuu, as well as one specific article from AmalgationSage and a whole lot of research into meditation and imaging techniques. The theory, which I'm working with the boys to test, as well as trying for myself,  is that if you can martial your mental defenses, you can keep him out of your head and survive longer in the process. Because as far as I can tell, he always breaks his prey's mental defenses, and if what happened to Amalga is any indication, it's quite possible that he can't get to you physically until he's gotten inside your head. Which has led me to a couple of different hypotheses that I need to find a way to test without it being actively suicide.
The first one, which is what I'm working with here, is the safest. It is, as I mentioned, the idea that if we can fortify our minds, he can't get in/we can kick him out. Which is why I'm really glad to have all four of us for this. We're all at different stages of being mentally affected by Slendy. Ideally we'd also have someone who's even further gone than Lucas, but this is a great place to start.
For obvious reasons I'm not going to get into EXACTLY what we're doing. But once we have results one way or another, I promise I'll give you details, and advice for how best to get started, if it seems to work. I'm wary of posting too much of the details of what I'm doing when it can still be interfered with, since I know three different proxies AT LEAST are reading this.

Edit: Here's what Lucas has to say
