I: But how do you know you're not simply imagining things?
She: I have no imagination! [turns away and walks away]
You've just had answered your question in the OP.
She does have an imagination, but is unable to distinguish it from reality as her reality now includes magic as a credible and valid concept, ergo, anything goes. The sky is no longer the limit.
The line between what is real and what isn't in her mind is now governed by her own personal agenda, driven by what she feels suits her best with her religion. And of course, that would be fickle at best, changing from day to day as she entertains any notion at all and fits it into her "belief du jour".
