The hidden cycle: dying, death, rebirth
In the Theravada tradition, when one dies, he/she is reborn immediately. There's no gap between death and birth. I think this confusion comes becauses of the stories about people floating around, looking for a suitable womb, after death. But those beings who float around can still see and hear. That means they have a body with functional senses. So they are born already into a new existence.
