Answering these without specific is examples is actually rather boring, and I'm not sure why you would take my word (though by all means, I'm an honest and forthright person) but here you go:
How specific? Extremely. I described my dream job (at the time) and person (at the time) to the absolute letter. So, 10/10. My living situation as well (though I didn't go into as much detail as the others).
How dramatic? Well, career, home, and relationship are pretty much the largest things, aren't they? So 10/10 again.
How not realistically explained by other means? Well, I was hired for the job and given complete control over everything with no college degree or any other traditional means. The friend I met my boss through also hardly knew him and met him through a contractor. Met, connected, done. I will give this 9/10.
I was messaged completely out of the blue by the person regarding the relationship (on social media... but before Facebook's time) having never seen or heard of them before. I'll give this 10/10.
As for the living situation, well, that was actually very conventional (although it fitting the specifics I had outlined so precisely seems pretty damn rare). I'll give this, I don't know, 1/10? 3/10? in this category.
There is more to the story in each one. For instance regarding the living situation there were fortuitous circumstances that made me actually realize what it was that I wanted, and then once that was decided, I went and got it done conventionally - the whole thing took only a week, most of it research - but what I found almost immediately in the search was absolutely perfect.
Regarding the job, as I described it was a spontaneous almost somewhat random meeting with my future employer, that had almost nothing to do with me being hired or seeking a job. Spoke to him over the course of a few days before the deal was verbally "closed". This occurred almost exactly 30 days after focusing on the manifestation. Then he went back to his work. I slacked off a bit but soon went back to focusing on it and 2-months later phone call out of the blue, bought me a plane ticket and I flew out that weekend and that's when it was of course "official". No contact with him in-between.
Also I get a very strong sensation, that I don't know how to explain, but I call it "swimming in probabilities" at the crux of these events. When my future-boss offered me the position (and shortly beforehand, probably around when he mentally decided he would be offering me the position) it was almost overwhelming, one of the strongest I've felt so far. I really don't know how to describe it, but it's unique, highly noticeable, and always seems to come on strongest during big life decisions. My head feels all swimmy, in a way like being drunk, but while sober and focused.
