Hi Sparkle, this was a good interpretation. I also thought that it could be that Mandy’s husband had second thoughts about this offer at Bloemfontein. The fact that the microphone was sabotage could reveal an inner fear (emotional restoration dream) that he would not be able to minister as he wants. He might have feared that he will be dictated or prevented from preaching and ministering as he should or wants to according to the leading of the Holy Spirit.
Mandy already indicated that her husband did relate to your interpretation which identified a slightly different trigger. You had it spot-on so well done.
