Part of developing a sixth sense is learning how to pay close attention to your surroundings, particularly to small or minute details. The more attention you pay to your surroundings, the more aware you become of slight changes and variations, and the more attuned you become with the world around you. Enhancing your perception this way helps you to notice subtle shifts and changes in your environment and eventually to anticipate certain things before they happen. For example, imagine a street you travel frequently. Try to imagine it in as close and as much precise detail as you can. Where are the various shops located? Which traffic signs are posted? What are the parking regulations? What kind of landscaping does the street have? Write down as many details as you're able to remember, then go visit that street and carefully fill in the blanks in your memory. Write down a detailed description of what you see. Later, test yourself to see how accurately you remembered the details you wrote down. Learn to notice and absorb this level of detail wherever you go. Teach yourself to focus your attention outward rather than inward. Doing so will help you develop sensitivity to what goes on around you and will teach you to quiet your own thoughts and preoccupations when necessary. Take a notebook with you when you go places. Note what you see and sense in as much detail as possible. Make this a regular practice until you find yourself doing it automatically, with or without the notebook. When talking with someone, train yourself to put your full attention on them. When you learn to observe someone closely and attentively, you often learn to pick up on small, nearly imperceptible cues that will indicate what the person is truly feeling or thinking. Note small variations in their tone and inflection, watch the movement of their eyes and the contraction or dilation of their pupils, pay attention to the words they choose, and notice the pauses and silences between their words. We tend to rely on our sight to interpret the world around us, so much so that sight can come to predominate over our other senses. But if you consciously work on prioritizing senses other than sight, you can begin to perceive more subtle variations in the environment of which you were previously unaware. Try closing your eyes and using your other senses to perceive people as they walk by. Note the sound of their clothing, footfalls, and breathing. Note their smell. Note the subtle changes in the air around them as they move. Note any temperature changes that occur as they pass. See if you can detect where their attention is directed and if you can tell when their attention falls on you. As you become more sensitive to people and the energy they give off, see if you can notice the particular type of energy of each person who passes. Can you pick up on any tension or on any negative or positive energy? Try to assess the energy of rooms you walk into. Can you sense any positive or negative energy?
Learn to notice small things. Record what you see. Learn to watch and listen closely. Exercise your non-visual senses.
