Hi. I do this thing where I'll just be going throughout my day and I just severely zone out. Like, I can see everything that's happening around me but I can't hear anything. I'll see that people are talking to me but there's no sound. And then after a few seconds, everything's back to normal. When this happens, apparently I get all pale, my head twitches, and my eyes roll back. And afterwards, I get a nauseous kind of feeling. Can anyone tell me what this could be because I've tried researching it an nothing I find fits it. I just want to know.
