I've always had incredibly vivid dreams, and it takes me some time after waking up to realize they're not real. Sometimes, it’s a disappointment, but generally I just forget about it and move on. Back in 6th grade, I had one really close friend, and we never actually fought. One night, I had a vivid dream where my friend and I had a massive argument over something I can't even recall now. I was really good at holding grudges because I was not a forgiving child, so for three weeks I completely ignored my best friend in anger to the point where she started crying in front of the teacher and he asked what was going on. As I was telling the story, I realized the events were really weird and that it had all been a dream. I went silent, stared at my still-upset friend, and had no idea what to say because I had seriously messed up.
