i have never heard of a single person who hasn't been able to attain lucidity, given that they didnt quite trying after a week or two...if you stick with it, and keep writing down your dreams, it will come. Also, you'll notice as your dream recall gets better, so will your ability to 'notice' things...right now you totally go along with your dream, because you're prettymuch remembering something that happened in your sleep upon wakening, but if you work at getting better at remembering dreams, you'll start to 'remember' your dream while its taking place, which gives you presence of mind enough to 'notice' things...

hope ive helped ^^...oh and, i dunno if anyone's done this for ya yet, but:
