Asking yourself in real life whether you're dreaming or not doesnt seem to be enough. I mean, i simply used to answer by yes or no, and simply move on...

From now on (starting March the 10th), i'll try to do RCs every hour and a half, which is the time when REM sleep starts. Hopefully i'll be conditioned to do quick reality checks eveytime i start to dream.
Instead of simply asking myself whether i'm dreaming, I'll try more to explore ALL my senses. I'll try to HEAR things my brain uses to ignore, for example the sound of my footsteps when i'm walking.
I'll try to be aware of the hundreds of people i cross everyday, not by looking at them (which would take a ridiculous amount of energy), but more by knowing they were there (hope that makes sense). It's unbelievable the amount of perceptual informations our brain neglects. Basically, these infos aren't necessary in our everyday life, this is why our brain neglects them (and maybe why we ignore them in our dreams.)
As for my other senses, i'll also try to be more aware of them. I tend to breathe through my mouth, which doesn't make me much of a smeller. I'll try to smell people (as discreetly as possible) . Also, the next time i put my hands in my pockets, i'm gonna feel the texture of the fabric from time to time, and so on...

To summarize, i'll just try be more aware of my overall BEING.
You are very welcome to start doing RCs this way, and hopefully it will improve our LDs Also, plz post whatever improvements you think is due to this technique.
