Maybe your energy level has been low for long and so you could feel VK's high power and energy more. As you know VK boosts your Aura and chakras around 300% as you wear it, so you must have felt the boost of energy in those chakras, aura, and body too. And your other family members may not be as low in energy as you were before wearing VK.
Another reason could be that you are more sensitive to energy than other people around. So you felt it high. For example, the flow of breeze is felt differently by different people based upon their own sensitivity.
