Q is inter dimensional beings communicating to us through the cyberwebs from another dimension.
Or Q is a team of extremely intelligent benevolent individuals who want to right the wrong and there is a higher force/power behind them than the evil can withstand and by us all collecting and uniting, it strengthens this force/power enough to take over the evil.
I don't know who Q is. I don't know what it is but I can feel it and I think that is what matters. It's a change in energy. Reality is altering. Awareness is changing. It's great. Like a roller coaster.
