There is most definitely a difference in the energy you feel in different places.  If you doubt this, step into a prison and then step into a church.  These are two ends of a spectrum, but the differences in vibration can be felt everywhere you go.  Certain geographic locations carry higher or lower vibrations.  Hotel rooms carry a mix of unfamiliar energies to you, just as your house carries familiar ones.  Become aware of the changes as you interact with different people, different places.  You are an energetic being.  Your body is made of energy, of light.  Your thoughts arise from this same field of vibration.  What do you wish to radiate into the world?  Think in terms of vibration and see how that changes things for you.  You are so very loved.
