Like we found by Moshe that he went up to the firmament as body and soul, and remained there for 40 days, so to it will be with the Moshiach after
he merits to that neshoma and recognizes himself that he is Moshiach, as it states Moshiach will be revealed but he still won’t be recognized by the rest of the people, and afterwards the Moshiach will be concealed in body and soul in the same way that Moshe entered into the cloud…
( Ohr Hachama on Zohar Shemos 7b, quong R’ Chayim Vital, z”l.)
It is explained elsewhere that “[the verse] ’Moshe entered into the cloud’ means that he separated from the ma‐
terial body”.
Ohr Hachama, Mishpatim 99a.
(This isn’t the part relevant to my vision/ dream. For the whole fascinating discussion of how our bodies will look by Moshiach’s time along with the list of sources, please see Edited)
The nekuda is that everyone will shed their flesh bodies (remove your shoes) and be left with our original bodies, the tzelem Elokim before Chet etz hadas, which was so luminous that it darkened the sun as is known)
As for my question about Aharon, I’m surprised it wasn’t obviously obvious, but since it seems it wasn’t clear- OBVIOUSLY i don’t think Aharon was stupid or harbored strange beliefs etc. for believing in the words of his Rebbe Moshe Rabbeinu who had told everyone he was coming back… and I’m gonna leave it at that for now, because what I was alluding to was a separate topic.
