I started getting lucid dreams very often during my exams.
here's what you need to do!

go to sleep at night whenever you normally do. then wake up a bit early.. like at around 8 a.m.
stay awake for about half an hour.. read the newspapers or something. (i used to get up and study) then go back to sleep. while you're falling asleep keep thinking of the newspaper or a computer screen in front of your eyes.. then you fall asleep slowly and you're lucid!

worked for me thrice in a row!

once you're lucid, think of a computer screen again and imgaine being pulled into it. everytime i'm fully in the screen, i feel vibrations and the lucidity becomes really strong..
