cats are great,one of my cats follows the same pattern I sleep with. I usually sleep on my side and he sleeps in the crevice under my neck and then middle of night, I lay on my back with my left arm out in an arch and he fits himself in there. I know what you mean about them actually sleeping on you, I have had cats that slept on my head or legs and its hard, my cat cuddles with me, man, I need a girlfriend-lol
