I was thinking about this yesterday. If VR ever becomes so real you can't tell the difference (like the matrix for example) you could become incredibly attatched to that world.

Have you ever had a dream where you're really happy, maybe you have a hot girlfriend or you're a millionare, then when you wake up and you feel abit dissapointed and sad when you realise it wasn't real? I guess it would go the same way for Virtual Reality. You could end up becoming attached to characters in a game for example. I mean come on, it's already easy enough to get attached to characters in movies/games as it is and feel abit sad when they die, imagine if it was Virtual Reality. You could probably fall in love with a character and end up becoming deeply depressed if something happened to them.

Still, I'm really exicited to see the advancements. I think VR is something we could see in our lifetime.
