Well, not to be argumentative, people who visit the afterdeath zone have witnessed people apparently 'resting'. At least it looks like that to the projector, but what they are presumably doing is going through their life review and 'recharging their batteries' and going through their adaptive process before going on to the next level. Some people take a very long time as they go through this process, depending on the kind of incarnation they had.
So 'resting' is one way to look at it, but it seems to be a part of the process to achieve that peace.
