I hate that annoying song thing. I was trying to meditate when Hey You by Pink Flloyd flew right into my head. I eventually got it to leave…But then 3 different Nirvana songs mixed up and played in my head. (On a Plain, Litium, Breed) It sounded like it would be called Breeding on a Plain taking Lithium. I just got fed up and stopped. One other thing that happens is I often fall asleep while meditating. It really sucks. I am starting to more get a hang of it recently.
