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. 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. Of course, as I’m telling the story I realize the events were super weird and that it was all a dream. I went silent, stared at my still-upset friend, and had no idea what to say because I had seriously messed up.
