When you go to sleep you can repeat the following mantras in your mind. it will tell your intention to your deeper mind. When you repeat a mantra over and over again with a pure intention and focus, your mind will treat it as something very important.

“I will lucid dream tonight.”
“I am dreaming.”
“I will wake up in a dream tonight.”
“Soon I will be dreaming.”
“I will have lucid dreams tonight.”
“I want to be fully conscious during my dreams tonight. ”
