I grew up in a time before the Internet. Yes, I'm that old! :p
Even so, I find much of my time is spent looking at a screen. My eyes blur, causing my brain to fog long after I should have, just switched off.
I can only imagine how difficult it is for your generation. It must be like living your whole life on-line? As you say, like a dream. Well, this dream is real and we can't wake up.
Is this true? I think not. It will take effort, but there is a world of reality out there. It may just start by visiting local landmarks, but it is outside where the physical relationships start. You need to experience the world to feel part of it. It's all about balance. You can live on-line and outside in equal measures.
