Have you ever felt like this?

I usually just live my little life. Getting things done, watching tv, studying etc. and sometimes a strange feeling just hits me as if I suddenly wake up for a few seconds even though I'm already awake. It feels like lucid dreaming but with existence. It's not consciousness because every human is conscious when they're awake. It feels something above that. Like next level. It's like seeing yourself and your life as a whole. Like your really exist above the usual existing and how you're seeing is above how you usually see your environment. I can't really describe it better. I only experience it sometimes and only for a few seconds then it goes back to normal. (Just to clarify, I don't do drugs and I don't have any mental illnesses.)

Has anyone experienced or heard of this phenomenon? What is this called?
