This is like asking what a real breather is or a real sleeper is... if it is done it is real... if it is not done it is just imagined. I am imagining a real hike right now. Right now I am not a hiker... I am a cyber hiker. Later on when I hit a trail, I will be a hiker. I used to be a welder, pipefitter, machinist, clam digger, trapper, etc... I enjoy fishing, hiking, taking pictures, etc... In trying to make it simple, I am complicating it.
Let me start over: If you are doing it, you are real.
