I experienced the same sensation earlier when I visited your Meet & Greet post, typed my paragraph about a new dream topic, clicked submit, then noticed all the other posts in this thread had disappeared (I figured it was something I did).
Turned out the conversation in your Meet & Greet thread is so long that it merited a second page! (The initial post is pinned to the top of each new page in the thread, I assume so folks can refer back and stay more or less on topic).
Scroll to the bottom of the page and you’ll see a tiny 1 and 2. Click back a page, and you’ll be able to find Mary Ann’s post.
