Linda,
I wonder if this is a dream signaling transition? You are going to a place that is “foreign” – you may not have been in this place before, but this is a new place and new opportunity that may seem strange. The envelopes are messages that have not yet been revealed/known but as you seek the Lord, He will reveal to you what is hidden/not yet known. Your time has not “expired” or come to an end. There is still so much for you to do and finish. You are still valid and are needed.
Hope this helps! Blessings!
