I had the same thing happen to me last night... I experienced pain in my dream.. Something was biting my hand really hard and something was also forcing me down and I couldn't get up. I have experienced pain before in my LD, but this time it was terrible!! When I finally was able to move - I got up and turned on the light in the bathroom and looked at my hand. My hand was swollen from where the biting had occurred. This is too freaky to me. I just don't know what is going on - it was so real. I felt the pain and the pain would not stop. This is not the first time I've experienced pain during a LD.
