Wait, I read the link too and I think I have heard of this. It actually is fairly similar. Here is my take...
Some people have died and come back to life with an after-death experience involving a demon trying to convince them that everything in this world is all an illusion. In some cases, the demon says it was made up by YOU... In which, Deva, is strikingly similar to your comments about living and creating on your computer.
This really appeared to frighten the hell out of these people when they cam back from the brink of death.
When I first heard this I thought to myself...
If I created all of this, then I am pretty darn creative and I don't think I would be scared. I think I would be impressed.
