Knowing what I'll dream about, how can I make it lucid?

Hey guys. Some weekends I go to sleep at my cousin's house, and normally before going to sleep, we play 1 or 2 hours of 'Black Ops' (split screen and bots on ps3). I'd say 90% we do this, the next morning I can remember a dream about Black ops (or war/snipers/weapons in general). I tried to convince myself to do a RC the next ime I was in any war-related environment. Altho I did dream bout war, I didn't get lucid.

What would I have to do to induce a lucid dream, using this as my dreamsign?

Another question: I speak spanish as my main language. However, I love english, and pretty much everything I read/search is in english; as well as my ipod, pc, phone, etc. I normally speak english in my dreams (which is amazing cos I speak so fluently on dreams unlike real life xD). If I use a mantra or something, what language should I use?

Thanks alot.

You should try and relate Black Ops to dreaming. So when you're playing Black Ops think to yourself "Is this a dream", do RC etc. and the same with a war environment. That way eventually your mind should automatically do a RC check whenever the topic of Black Ops or war comes up (Although that would be pretty difficult).

When you remind yourself, picture it happening. Imagine the whole scenario. Imagine what you think the dream will be like, how you will become lucid, how you will reality check, and what you will do afterwards. This will help lock the intention in your memory. This is similar to the way you remember to do anything in life. Picture yourself doing it as you are telling yourself you will remember.
