Christmas-- A big occasion
Wedding dress -- A big occasion for you
Wrapping presents -- Presents for others
A Priest-- A priest in a previous incarnation showing himself. The higher of the group gathered.
Tourists-- other disincarnates come to look and possibly learn(which they do)
Not this door but the other -- You may observe but you are not part of this at this time
Third and fourth days-- numbers three and fou,r perhaps days, months, or years.. time anyway.I'm not sure of the verse content in verses three and four, perhaps if you found that out it would zero in a bit more?
All kinda guess-work but I get the feeling....
