Everything is energy. What we see and touch is just energy vibrating at a frequencies low enough to create matter. Things we can’t see, such as sound, are higher vibrating frequencies, yet still energy. A super smart dude by the name of Albert Einstein noted, "Energy cannot be created or destroyed, it can only be changed from one form to another." Energy can shift it's vibration, so what we tend to judge as good or bad, exciting or boring, black or white is literally energy
