I woke up from a dream and felt like something big just happened. Like the world just ended or something. But everything is fine?

So today I woke up around 7am and felt an amazing sense of relief, like a huge burden just got lifted off of me. But everything is fine? I seriously almost thought something BIG just happened overnight. Like the world just ended or something, but I don't see anything. Nothing happened. But the feeling is gone now. Everything feels normal. It was so strange. Has this ever happened to you before?
