Sometimes I know what you mean, Riley. What usually helps me is keeping a pen and paper nearby or pulling out my notes on my phone. I’ll have this rush of ideas and then they’ll be gone if I don’t do those things. I had an experience similar to that. I was at a concert last weekend and out of nowhere this bit of inspiration hit. I kept replaying it over and over in my mind, while still paying attention to the music. The music is what actually helped me to remember. I started typing things out on my phone that night after and then wrote it down on paper the next day.
