I find that knowing is half of the battle and one of the tips for lucid dreaming is to understand some facts about the subject. So here are a few things that you probably didn't know about the life-changing experience.
When You Close Your Eyes In A Lucid Dream You Wake Up
Remember when you were little and you used to have nightmares and to get away you would shut your eyes tight and scream "WAKE UP!" and you would awake in the safety of your own bed.
The same goes for lucid dreaming if you shut you're eyes even accidentally (you don't blink in lucid dreams) then you will wake up and return to your physical body. If this does happen you can go back to your lucid state by shutting your eyes as soon as you wake up staying completely still and you will quickly fall back with full control of your dream.
