What is stream of consciousness? Does it mean just writing down what's going on in your mind and doesn't have to reorder the sentences to make them focus on a topic? My mind is pretty messy, and random thoughts keeping coming up, from one to another. Right now I don't even know what I'm talking about. Does it mean I have a popcorn brain? Hell, I don't even know what that word exactly means. I heard it from someone and I'm too lazy to look into its meaning. However, it feels so good that I just write down everything without worrying about grammar or logic, and that I don't have to rephrase everything to make it smooth or perfect.
