Communion of the dying

There's the communion of the living. Human beings alive at the same time, who collectively experience the life on earth. 

There's the communion of the dead. The fellowship of the saints in glory who collectively experience heaven. 

Their counterpart is the fellowship of the damned. Hell may be compartmentalized, so that perdition varies. 

There's the communion of the glorified The fellowship of the saints who collective experience the world to come, on a renewed earth. 

There's the communion of the dying. I have in mind those who are lucid. The psychological experience of withdrawing from the world of the living. Who begin to withdraw psychologically before they withdraw physically. Or gradually withdraw in tandem. 

Unbelievers may react to this very differently from believers. But there's a shift in identity, where the dying have a special affinity with each other. Where they relate more to the dying, through the experience of the dying, which they now share in common, than to the living. It depends on part on whether they have the grace to cope with their impending farewell.
