yeah i get this. But they tend to be weak images (as in not very vivid) but very strong audio...er things. Like i will clearly hear things like rain as if their actually happening. Or doors opening and closing, or sometimes, but rarley people talking. It doesnt happen very oftern. Usually only if i NEED to sleep. And the only time i need to sleep is for work. Ive also found it works if i dont just lay there, but if i actually diliberatley try to make it happen. I have a problem with my eyes, where i can just shut them at rest, so i have to try and sleep in a pitch black room to simulate my eyes being properly closed. I find when i do this, the audio things in my head get more intense, i suppose its a way of my brain trying to make up the fact its like ive lost two of my senses, sight and sound. But its amazing what your brain can do init? Its like some kind of alien technology thats not yet being fully tapped into. Or something like the PS3, the technology is there, but it hasnt being fully taken advantage of yet. A stupid analogy, but i know what i mean! LOL :p
