I find that I get lucid dreams when I start to question if I'm dreaming (i.e. when my logic kicks in), so maybe you were just semi-lucid? Because I've also had a lot of dreams that I realised I was dreaming but couldn't care less (i.e. my logic hadn't kicked in). In a perfect lucid dream, you are both fully aware and in full control, so if you think you might be lucid, just act like if nothing were different from real life. If you enter your dream with preconceived notions of limits to your dream control, then you are screwed from the start .
