Sorry but wrong. Once you meditate and build up your vibrations, stay away from alcohol a few days before you intend to Lucid Dream, not eating meat also helps. Just like nightmares, if you attract negative energy in your sleep it will manifest in Lucid Dreams. Also if your afraid or nervous you will manifest your fear. Like anything, you need to know what your doing! You wouldn't take a huge chainsaw to a tree unless you had training would you?
