Having a vague sense of foreboding is generally an indication that the devil sees good things on the horizon, and he and his comrades are trying desperately to cause you to feel fear and trepidation. He wants to use the fear to block the things that God has decreed. Whenever you feel uneasy, instead of giving in to fear, speak God's truth over your life and over the future--that all will be well in the millennial kingdom of God.
There are many ways that the devil and his comrades can cause you to feel a sense of foreboding. First, they can cause you to be surrounded by demons, thereby blocking the flow of your energy and increasing your sense of anxiety. Second, they can use Smartphone apps to radiate you and block the flow of energy in your stomach region. You may not even notice the person standing ten, twenty, or thirty feet away from you, and pointing their Smartphone at your stomach and/or your chest. They are usually instructed to do so by their spirit guides who are almost always demons from hell.
