The new thing you should practice: reading the vibrations that surround you.
In "The Science That Will Change Your Future", Dr. Bruce Lipton talks about how everything in life communicates through vibrations. We can simplify everything, even to the atomic level, to good and bad vibes. Before you snort at the person who says you're giving off bad vibes, maybe consider this first. Dr. Lipton talks about how the gazelle doesn't go up to the lion and asks, "Are you my friend?", instead the gazelle can feel its bad vibes. How can the gazelle do this?
Vibrations do one of two things when they interfere with each other: mesh or clash. Good vibes are vibrations that mesh together. Bad vibes are vibrations that clash. The gazelle can sense its energy clashing with the energy of the lion (he terms this as destructive interference).
Dr. Lipton talks about how we are trained to not sense these vibrations. We see animals do it! Some people will tell you that cats just don't like them, for whatever reason. I have had many friends who said that if their dog didn't like you, then you probably aren't a good person.
Animals base everything off of their intuition to these vibrations; it is their key to survival. Everyone knows that dogs and cats can't see color. But have you ever really watched your pet? How their eyes dart around the room, or they growl at nothing? They are seeing things we aren't able to see. They are sensing vibrations in the room that we are not capable to sense.
What does any of this have to do with classifying yourself as a dreamer?
Those who are classified as dreamers are mainly those who pursue careers dealing with their artistic abilities. Having artistic abilities means you are more in-tune with not only your emotions but the emotions in the space around you. You are more perceptive of others and your surroundings. Thus, you are more in-tune with the vibrations that your art comes from. Your brain makes a neural connection between an emotion (a vibration), and what you produce (your art).
If you are a dreamer, you are unrealistic. You are perceived as driftwood; floating on idealism. If you are stiff and follow a designated path, you are practical and considered a "realist."
But who is more real? The one who ignores the vibrations in their environment; the businessman guiding the Caterpillars? Or the dreamer, who not only recognizes the vibes, but is able to portray them in a way that others can not only comprehend, but feel in their own ways?
