Twin deans? Or shared dream?

So I’m not pregnant yet but I’ve been trying for a couple months. A few months ago my sisters (2 of them at least) and I all found out we had the same dream. I called one of them and told her I had a really weird and vivid dream that I was pregnant with twins, she told me she had a dream where she was doing the gender reveal party for me being pregnant with twins, and then our other sister came in the room and told us that she also had a dream where I was announcing to them that I was pregnant with twins. Has anybody ever had this happen to them before?
