To me it means knowing what will happen before it happens.(rephrasing optional)
Buddha was known by the adjective of "Tathagata" i.e. a person "who has been there and came back". A person who had Spiritual Experience that liberated him from all bondage but who came back to enlighten the rest of the humanity about it.
So if you mean by"being there and back" any spiritual experience,most of us will not be so blessed.
But if you are talking about precognition/some supernatural experience, many of us will claim that they had been at the "cutting edge".
