In the late 90's I think, there was a movie where a neural device was created that allowed anyone to "record" their brain activity so that it could be replayed later by anyone with a device for that. But it became like a drug as people got addicted to it and couldn't stop living the virtual experiences of others (this was a long time ago so I hope I remember the story correctly)! Some people wanted to experience murdering someone, or having sex with a famous person... cool stuff :D Anyone knows which movie was that?
Anyway, this feels like the beginning of that.
