I had a lucid dream and someone i know told me that they can make machines to cause them but it causes bad dreams. Is this true?
i don't think there's a machine...that would be awesome if there was...anyway, you can train/teach yourself to lucid dream if you want to experience it again-check out this website on a brief how to.. http://www.luciddreaminghowto.org/how-to-lucid-dream.html
It is not true that there are machines that are used to make lucid dreams. Lucid dreams happen when the dreamer is aware of what they are dreaming. However, there are no known machines for creating lucid dreams.
