well, let me hang in this debate ;)
@Granby: well, depends on which state of the human being you're referring to. It's a fact that our brain is working way more while we sleep than while we're awake. This is the first thing. Secondly: Movies like Butterfly Effect are aweseme and interesting, but nevertheless it's still fiction. There is no proof nor any kind of belief that this is possible in our daily life, since we'd have to travel in time for that
By the way if you like movies like that, you'd enjoy a movie called "Limitless". The idea is similar and it's closer to the reality than Butterfly Effect ;)
btw, if you want to discuss things: sure, just go and start a topic, I'd appreciate any form of that. You could even start an discussion thread for that, so we dont have to bomb the FreeChat for that
