Lucid Dreams and YOU

I came across a link on stumbleupon that explained how to lucid dream (http://www.stumbleupon.com/su/273ha2/humor-image.com/how-to-control-your-dreams/) so I began following the instructions and combining them with other methods I read online.  In addition to what is explained in that link, I also have tried laying perfectly still in an attempt to trick my brain into thinking I have fallen asleep (read that this works) but after roughly about 30 minutes, my body felt extremely heavy, it felt like somebody was sitting on my chest so i gave in and moved about.  Still no lucid dreaming has occured, am I missing something?
