時空交錯

YES, have you ever felt that at any point in time that you don't really know where you are at? Its interesting when it happened, suddenly I felt like I have woken from a dream that I didn't know I was in a dream and the boundary between reality and dream is so blur, so blur that you will question dream as to reality or for that matter, reality to dream, afterall, can you really say you are not in a fantasy land and not the total truth?
