yeah i used to get that with my mates years ago smoking strong stuff. patterns you get when you close your eyes are like what the others are saying..... you are tripping off it. sex with my wife getting back was also awesome in that state. music will sound lots better and also experiment with different stuff for just smoking too. most of all dont think you have to smoke as much as them take fewer puffs etc. enjoy the weed smoking experiance just dont overdue it fella!
