Actually what's really interesting is that you only feel like you need to breathe from a build up of carbon dioxide NOT a lack of oxygen. So, as long as you breathe fast enough to saturate your body with oxygen, if you were to deep dive and not feel like you had to breathe you should be fine.
It's the same reason sudden deaths happen in things like septic tanks. You climb in and keep breathing, so your body thinks it's fine, but you suffocate anyway.
