Three days ago I ran into a light poll while I was running and blacked out for just a few minutes. I came to and my roommate tried keeping me concious, but I don't remember any of our interactions or even what had happen until they told me the next day. I have pain and bruising above my left eye and slightly under it. I'm a smoker, and two days later I noticed smoking making my stomach feel kind of unsettling and giving me a slight headache. This has never happened before. I've also had difficulty dreaming as well as lucid dreams when I usually didn't dream before the accident. I also saw a figure when I woke up from one of these dreams who didnt go away until I turned my light on after I had swung my pillow at it and screamed. May I have some sort of brain trama?
