Period Dream/ Missed Period/ Possibly Pregnant

Last night I had a dream that I went to get in the shower, stripped, and black/brown blood went all over the floor. Soaking the floor. It was more like a nightmare. My period was supposed to start 2 days ago. But today, I have brown discharge. Not even enough to get on my underwear, I wear a panty liner to make sure. Has anyone else had a period dream, but turned out pregnant? It just has me tripping out.
