How would I set the messages buffer to record the history of every folder I
have gone to in my current session?

Gone to how?
Maybe option `find-file-hook' or `dired-after-readin-hook' will help you.
(But why would you want to drown that history in a sea of other, unrelated
messages? If you want a history of accessed folders, why not put that in a
separate buffer?)

"Accessed folders", which includes:
(1) M-x find-file RET usr/include RET
(2) M-x find-file RET ~/study/literature.org RET

Good idea. After (1) and (2), the separate buffer would read:
/usr/include
~/study

Emacs already tracks this information, no need to add hooks.
(defun get-session-dirs ()
"return list of directories visited in session"
(delete-dups
(mapcar (lambda (f)
(file-name-directory f))
file-name-history)))
List of directory returned is in reverse chronological order.

How would I insert the returned list into a buffer?

I think it's time to crack open that Elisp tutorial you're talking about:
(defun session-dirs ()
"return list of directories visited in session"
(delete-dups
(mapcar (lambda (f)
(file-name-directory f))
file-name-history)))
(defun display-session-dirs ()
"show list of session dirs in a buffer"
(interactive)
(pop-to-buffer (get-buffer-create "*session dirs*"))
(erase-buffer)
(insert (mapconcat 'identity (session-dirs) "\n")))

And that list is only a snapshot taken at one moment.
I think the OP wanted a log, with the log being updated each time a dir is
accessed, so that it always accurately reflects the access history.
Hence the use of a hook. That's what hooks are for.
You can use another kind of procedural attachment, or create another kind of
trigger, or even use a timer (modulo some delay in reflection).
But some such mechanism is called for if you want to attach/couple an access
event to log output.
