i find that when im falling asleep and trying to concentrate on the imagery, i dont know WHAT to concentrate on. it feels like i have many layers of images to look at...there are fuzzy dots floating around directly behind my eyelids...there are images of people and places flashing in my head...among other things. what am i supposed to be focusing on? the fuzzy dots and shapes floating around behind my lids...or the images that feel like, theyre inside my head? It's extremely hard to concentrate on the shapes because they come and go so fast, and it kind of gives me a headache trying to focus on them.
