I don't think it is anxiety, I've been paranoid before but this is different. I can relate ilovelife when I smoke then get comfy I get numb all over and it feels like I am flying espsially with my eyes closed. I get that thinking your a genius thing too. My thought on it is possibly parts of your brain usually reserved for sense of touch and motor skills is being recruited elsewhere, if this is true then cat scans should be able to verify it. I have noticed that a cigarette will end the tripping phase and bring me back to reality, but music will take me back there.
