A while back, I was smoking a cigarette around 4 AM and all of a sudden my sight started blacking out and I told my boyfriend, at the time, that I felt like I was about to pass out. Right after that, I hit the ground and as soon as I woke up I didn t remember where I was. When I asked my boyfriend what happened he said I passed out and it looked like I was having a seizure? Is this reaction a seizure or? I ve also been but by my dog and it made me pass out on my kitchen floor. My mom told me I was slapping myself in the face and she was taking me to the doctor, while in the car she said I tried unlocking the door and getting out while the car was moving. I have no rememberance of the scene when I was bit by my dog. Why?
