In a decisive, scary, or potentially dangerous situation, we have all have experienced a "gut felling" about what our choice of action should be. It is uneasy feeling in the pit of your stomach that tells you something is wrong.
There is nothing supernatural or psychic about this feeling. It is just your body's first reaction to adrenaline entering your blood stream. Your body is getting a shot of adrenaline because your brain has determined that you are in danger. As your digestive system is being shut down to allow more blood to flow to your muscles, you get a queasy feeling in your stomach. Your subconscious mind has picked up signals of danger that your conscious mind has yet to recognize. For this reason, you should always trust your gut feeling.
Even if you are unable to determine what caused the "gut-feeling" of danger, do not dismiss the feeling. Always trust the feeling. This instinct was developed by our prehistoric ancestors as a way to survive. They trusted the feeling. That is one reason why you are alive now. To remain alive, trust your gut feelings.
