I have this question, I always daydreaming (accessing right side of my brain) alot but couldn’t remember anything of it later? Usually, I would blank stare at the blackboard during a lecture and only startle by my lecturer when they ask me whether I could follow. Also friends would make annoying remark at me, saying “Are you listening to me, I am talking to you, why are you daydreaming so much?” But I could never remember where my mind went.
