Your ‘vibration’ is a fancy way of describing your overall state of being. Everything in the universe is made up of energy vibrating at different frequencies. Even things that look solid are made up of vibrational energy fields at the quantum level. This includes you.
When a stronger vibrating source of physical, emotional, or thought energy is introduced to our system, it induces us through the process of resonance to come into vibrational “tune” with that stronger vibration. At that point, the energy in question can no longer function as we need it to maintain healthy balance.
