I have never heard of FC, but it seems that if it did work, it would require a "facilitator" who is honest and ethical and perhaps rational. Not sure if this woman qualifies.
The issue becomes the subconscious of the facilitator. Even if the disabled person was just going at random, the facilitator is going to subconsciously try to make sense of the random, and probably can come up with something that makes sense at least five times out of ten.
It's kind of like taroh cards, because you have so many open ended meanings in each card, you can make something out of nothing from a pile of them. In this FC you have 27 letters plus punctuation keys, and the entire English (or which ever) language. If you look hard enough for a pattern, you can find it, even if it doesn't actually mean anything.
I think this woman may have been very mixed up and honestly did delude herself into thinking she was in love. That doesn't excuse her actions, but it does go to show how people will latch on to something like this out of desperation for meaning in something they don't understand or refuse to accept.
She was desperate to love and be loved by someone like her creation of DJ, so she made DJ into that person.
