Some time in the distant past, the nature of dreams changed. You can still speak to those first dreamers. Afterall, when you die you just dream forever. Still, their memories are a bit fuzzy after millennia.

Welcome to wakefulness, the world where dreams are every bit as real as the waking world, perhaps even more so, afterall dreams are forever. The waking world is just temporary. People might abandon it forever if it wasn't the only place you could have children.

That too may change though. Experiments are afoot and that last barrier may be broken. If it is, nobody knows quite what will happen.
