Dreaming or astral projection?

If we were telepathic we could gather information without leaving our body, at all. Like an Internet on a broadband mobile signal. We could gather out side information from the world. And feel we had projected

I'm not saying this IS how it works BUT it is easy to grasp this because we have the technology to have this when we play games in 3D world's on-line. Yet the brain is supposed to have fallen together on it's own by mistake yet hasn't developed a mobile phone feature yet? Or perhaps prefers to leave it switched off?

Mmm someone might say “if you have nightmares I wouldn't want your brain phoning mine!”
