This will not be a deep, insightful post. As I was getting out of bed this morning I had a number of thoughts about a topic I've been thinking about all jump into my head. All at once, in a split second. As I went through the day I thought about these thoughts and, while I didn't come to a grand conclusion, I did feel like I made some progress in my thinking.
As I tried to write the thoughts down and record the experience I realized what happened. I had had a flash thought! Just like the flash mobs that appear, except this was my thoughts that all gathered in one split second in my brain. Flash thoughts!
