Dream of electric, hands

I was on a team of workpeople and there was one adult that was with us. He was maybe in his thirties and i felt a connection with him like we were close. However, i was the only one who noticed him turning evil as he sat at his desk and was working. His hands were creating electric shocks, and nobody else saw this but me. And i'm actually scared of electricity too. Then i saw his face go evil and he was like in a trance. and then the lights started to flicker on and off. He was turning into a villain.
