I have no idea what could be causing this. I access the site from two different computers at the moment, and have no problems like what you're describing. Wish I could help! Could it have something to do with the service you use?
As for the Dreams thread, it's having the same problem that the first Annoying thread had for the longest time. From what I can tell, it happens when, in an existing thread, the first post on a new page is deleted by its author. The forum thinks that new page is still there, although it recognizes that there are no posts on said new page. Forever after, the page count is thrown off because the forum continues to count that deleted post when numbering pages. So whenever a page gets filled with posts, the forum automatically thinks the next new page has already been started, while at the same time recognizing that there are no posts on said "next new page". Follow me?

Anyway, it's just a glitch in the system, so don't worry that it's your comptuer messing up.
