if you try to imagine something that's emotionally implausible to you, you'll likely fail

How do you mean that? I often find myself imagining things that are totally implausible emotionally, but quite possible physically, for instance, once in a while I imagine throwing myself off a bridge that I'm crossing, and I can feel my guts churning. (When I say "imagine" here, I mean I actually visualize myself falling, it's a stronger thing to me than idly considering the notion of falling.)
