this sounds similar to the 2nd time i got high, it was more of a relaxed and chilled out high and i wasnt rolling on the floor laughing like the first time i smoked. I was depressed for like a week and almost felt like my mind was on autopiolet, i would move without thinking about it.. it was weird, i would sit in class and all of a sudden out of nowhere it would feel like i was high again and it freaked the shit out of me but after about a week or so i returned to normal again. I guess this is just your mind and body getting used to the thc. hope this help u out.
