Do you ever find yourself in a state where you're so tired you're already partially immersed in the dream world, but also semi-conscious and perhaps still in the middle of carrying on a conversation with someone?

This has been happening to me a fair bit this year. Last night I was falling asleep while sat next to a friend, and we were talking, but I was also convinced by my subconscious that I was in the setting of a John Steinbeck book, on a boat in the Gulf of California. It wasn't until I said something to my friend about decks and dip-nets, trying to report this news of newly acquired collecting supplies from my dream, that I realized. He asked "Uh, what?" and I ended up repeating myself three or four times thinking it was just one of those instances of him not understanding because I spoke too fast/unclearly and he's not perfectly fluent in English before I realized it was actually that I was half-dreaming and talking from my dream. Another time in this state, I kept insisting to my then-boyfriend that he had to stop trying to kiss me because we were in public (in my dream) and isn't he against PDA?
