Hi ChrisS
I don't usually try to advise on peoples dreams but as you have asked I wondered if this could have been an opportunity using your current reading to give you a little teaching.
What stuck out here was someone of authority asked you to tell him what you could hear. You heard a heart beat. You then had to repeat this finding to others. Maybe the repeating of what you heard was so you would remember the words. You were listening to a heart beat. You had confirmation that you were right by being given 86%
Maybe the teaching here is for you to Listen To Your Heart. From that you could say , follow what you think is right, or live from the heart
( I was once advised to "Search For The Heart Of The Universe"
Thats just my feelings on it but others may have a completely different view.

I usually find that if I am confused with something but feel its important I send out a clear message asking for further clarification, and it comes!
