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. In 6th grade, I had a really close friend, and we never had any fights. One night, I had an incredibly vivid dream where my friend and I had a huge falling out over something I can't even remember now. Being excellent at holding grudges as an unforgiving child, I ignored my best friend for three weeks in anger, until she started crying in front of the teacher, who then asked what was happening. As I was telling the story, I realized the events were really weird and that it had all been a dream. I fell silent, looked at my friend who was still extremely upset, and didn't know what to say because I had messed up so badly.
