I don't think it's about being high simply because he says "now it's a gift and a curse since my birth". I think it's about the subjective reality that we all experience due to a combination of our expectations, what we remember, and how we perceive reality ourselves. Everyone's subjective reality is different. Some people experience a reality that is closer to objective reality than others due to a variety of factors. Also, the objectiveness of one's reality can change over the course of one's life. What he is talking about is being in a reality that is very far from objective reality. He's been there his entire life. He knows the bad side to it all, but after living this way as long as he has, he's grown used to it and now sees the good side too and has learned that it's not as bad as he once thought. He feels like since he's been there his entire life he's trapped with no way out.
