Dreams and illness

Dreams can be really shit sometimes. I had a dream that my ex was really horrible to me, and despite me knowing that that didn't actually happen, the feelings from that dream are still staying with me and it'd hard to shake them. I'm also feeling ill at the moment, which isn't helping. Everything aches sooo much! My glands are all swollen, swallowing is painful, and moving my head really hurts. I'm also just feeling really emotional and weepy today. I don't know if that's to do with the dream, or maybe my time in my cycle. Either way, I just want to cry and sleep all day.
