What does unspoken Really mean

At a church I recently visited, as part of the service. One person raised their hand and simply said they had an “unspoken request.”
Though I’ve not heard that phrase in a long time, it was a common utterance at a church I once attended. It was almost always said by women, and it always puzzled me. What exactly was behind such a statement?
In considering how it was said, with the body language and tone of voice behind it—ranging from emotional turmoil to smug self-satisfaction—I formulated several possible interpretations:

• I am too embarrassed to say this aloud.
• My need is too shameful to mention.
• I really have nothing to share, but want to call attention to myself.
• I want to be mysterious and garner unwarranted sympathy.
• My request is not appropriate to share in a large group or in mixed company.
• I cannot put the pain in my heart into words.

I think at one time or another, each of these were a correct understanding of the motivation for the person who uttered this ambiguous phrase.
As for the person who said it most recently, there was definitely a deep emotional pain behind it. I doubt if they could have said much more. In this case I was glad to pray for them— I even felt compelled to do so.
