I've always had super vivid dreams and it takes me a while after waking up to realize that they're not real. Sometimes, it's a disappointment but generally I just forget about it and move on. Now, in 6th grade I had one really close friend who I never actually got into a fight with. One night, I had a really vivid dream where my friend and I had this huge falling out over something that I can't even remember 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. Of course, as I'm telling the story I realize the events were super weird and that it was all a dream. I fall silent and just look at my friend who's still extremely upset and don't know what to say because I had fucked up so badly.
