These words are from Dallas Willard in his book Divine Conspiracy:
Another picture is of one who walks to a doorway between rooms. While still interacting with those in the room she is leaving, she begins to see and converse with people in a room beyond., who may be totally concealed from those left behind. Before the widespread use of heavy sedation, it was quite common for those keeping watch to observe something like this. The one making the transition often begins to speak to those who have gone before. They come to meet us while we are still in touch with those left behind. The curtain parts for us briefly before we go through.”

I hope you find this comforting like I did.
