hi. i've just woke up from the most terrifying experience of my life. It was only a dream, but I feel overly confiident that I could've died during this experience. In my dream I was hanging with my friends smoking when all of a sudden I felt a very real, and painful "numbness" I suppose in my head. This came and went in my dream and caused a lot of alarm. Everytime this happened, maybe a total of 4, I couldn't speak,and I went partially blind. and my thoughts felt very fuzzy so it was impossible for me to communicate this issue with my dream buddies. Anyway on the 4th time this happened my heart began to beat completely out of control, I would estimate 200 bpm. It was incredibly intense. This is when I woke up. my heart was still beating way out of control.I looked at the clock to see that i'd only been sleeping for 30 mins, but it'd felt like days. I am still shakey from this scary experience, as i've never encountered so much pain or had such a fast heart beat. My heart still hurts. Could I have died of heart failure? what happened?
