Peace to you,
Here again:
If someone today came to you and talk to you about his imaginary friend: an entity from dimension 7.
About how he sees him and hears him vividly.
That was chosen by this entity because he was special(has some weird anomaly in his brain that makes him suitable to talk to beings from dimentsion 7) to warn humanity of an impending danger that is heading our way: a malevolent conglomerat of alien species is coming to earth with nefarius goals in mind.
And he is very disorganized in speech or thinking(rapidly switching topics, called derailment or loose association; switching to topics that are unrelated, called tangental thinking).
Q: Would you think for a second he is mentally ill?
Maybe. Or maybe he is listening to a lying spirit (since the things he is saying are not true). Or maybe a combination of both. Or maybe he just misunderstood what he did hear.
Lot of maybes; but not much to go on either.
Would a psychiatrist suspect he probably is suffering from a psychotic disorder?
Maybe. Not being a psychiatrist myself, I can't really answer that question.

All that being said, you can't take this example and apply it to Christ if that is your intent. You can't apply your second point (rapidly switching topics; etc) based upon words from him that you have read. Not when you do not have the tone or inflection, pacing or pauses, eye contact, audience direction, body language, emotion, etc, to go with those words. Any of those things could indicate a natural progression into another topic (if indeed another topic was even being broached).
Not that a single or even couple of examples of quickly switching topics can possibly indicate that someone has a mental illness. Not everyone thinks the same way; regardless though, I suspect that most people have done this at some point in their lives.
Peace again to you!
your servant and a slave of Christ,
