Fears are a natural part of life and are designed to protect us from hurt and pain. If, for example, you have an experience of almost drowning in the ocean, your mind may cause you to be afraid of ever going into a body of water again. The chances of you having the same traumatic experience in the water again is minute, but the protection mechanism in your mind doesn’t want to take chances. Your subconscious mind is now programmed to avoid that situation and the pain and hurt associated with it. So, now, almost any body of water will be associated with the incident and fear will set in to avoid having the pain and another bad experience.
Let’s take another type of situation. Let’s say you had been in a relationship in which your significant other cheated on you. Perhaps he/she would announce that they were “going to meet a friend for drinks” and you later discovered that it was during each of those times that they were unfaithful to you. Since the subconscious mind is always looking for meaning and creates meaning through association, it simply links these two things, “going to meet a friend for drinks”
