What’s wrong with me?😰

Okay so for like a few weeks every once in a while I will just zone out and when I realize I zoned out my grandma (lives with me) will be like “where were you at” or “what are you thinkin bout” and I’m just like “huh” “what do you mean” then she’s like “you were just staring what were you thinking about” and I literally wasn’t thinking about anything I was just staring at nothing for no reason. Well today it was super weird and actually scared me cuz when I came back my grandma was saying my name really loud over and over like freaked out and she said she had been saying my name for a while before I responded. I faint a lot so she’s used to that but she said my eyes were open and I wasn’t blinking or moving just staring at the wall like I wasn’t even in my body it’s so weird. I can’t remember her trying to get my attention or what I was even thinking about I try so hard it’s like I was asleep for a few seconds but my body was still awake and my eyes were open. So weird. But anyway if this happens to you or if I should go to the dr please lmk cuz I’m stressing.
