It seems that you fall prey to the "typical mind fallacy". For example, some people thought imagination was just a metaphor, not something that people actually do. Turns out that people have different capacity of imagination. I don't experience exploding head syndrome though. Speaking of atypical mind, sometime I experience my vision become white entirely for a few moment. They are so brief that I am not sure that they occurs or they are just my imagination.
