What do you think of Emmanuel Swedenborg's insights into heaven and hell?

Both heaven and hell exist in our life, no need to go to other dimensions/realms... The one who has done lots of good acts in past, lives in heavens right now.. Because life is like a heaven for such person. Contrary, some suffer results of their own bad acts. If this suffering is really big, we can say this is a hell. Hell and heavens come and go several times during every person's lifespan.
