Was That Really the Holy Spirit?

I know that we should always judge what we experience by what the Bible says. An experience that did not come from Him must come from somewhere else.
But when I read something like this in my comments on preaching I’m left with a question:
Will do! My daughter has to preach in four different churches EVERY Sunday – one of them in a foreign language. Well, foreign to her. She has six parishes in all. But I know that once (at least) she felt the Holy Spirit prompting her to preach quite spontaneously on a different subject to the one she’d lined up. I’m sure He’ll do the same for you if necessary.
So, my question is… if I don’t believe the Bible supports women in the ministry, who gave this woman’s daughter the words to say? Or, to ask it a different way, if she attributes the call of the Holy Spirit to a natural phenomenon, what does that say about others that do the same?
This Labor Day weekend, my family visited a Jellystone park a ways from my home, and this was the first time that my children had ever been exposed to Yogi Bear. I mean, they saw the guy dressed up as Yogi Bear, and had no clue who it was.
