Scientists have tested this. You can read about it here:
Can Your Heart Predict the Future?
They concluded that intuitions about future events partly reside in the heart, and the signals from the heart to the brain are what we call unconscious “gut feelings” or hunches.
Here is a quote from the article:
“In other words, phrases such as ‘Listen to your heart,’ ‘Follow your heart’ and ‘I believe deep in my heart’ are more than metaphors: They are literal descriptions of what happens when we have intuitions. Another way of looking at McCraty’s findings is that many of our ‘gut’ feelings are actually ‘heartfelt.’ ”
I am taking it a step further and say that the gut and heart are allies and both contribute their part.
