Yes, thanks for that! I find it helpful to see other experiences like this because it makes me realize I've had similar things happen during hypomania. I looked in my journals and noticed I have documented some of it. Normally I only write a few words about how I'm doing but when I'm hypomanic it tends to turn into a long semi-coherent rant. As long as it's not too bad I find the tangential thinking can actually help boost my creativity, but when dysphoric it can get pretty intrusive.

Somebody else mentioned having fictional conversations in your head, and I've had that as well, to the point that I lose track of my surroundings and it almost becomes real. I have my eyes open but I don't really see anything anymore, I'm all caught up in my head. I don't know if that's related to racing thoughts or not but I've noticed it gets worse during episodes.
