I had a dream and it still vivid to me today. The dream started when about the 1800s and I was talking to a man I have never met before and I started coughing so I looked at my hand and I saw spit but he saw blood and freaked out. He led me up a hill to a black community and called to a John. John told me to lie down and he put ice on my nose and chest. It stopped my coughing but not the blood it still flowed. I have no idea of what it means and it's kind of bothering me.
