text: All of them... just leave the lights on. If you turn the lights off you'll be in total blackness... empty, lost, and without protection...\n\nThat's not true. Just stop watching those silly movies before you go to bed and quit playing those wild video games. Plus, try to eat a balanced diet -- junk food can mess with your dreams as well. Also, play some relaxing music, no rap or metal, before you sleep. \n\nActually, when I was young I used to have wild dreams. Some of them were very scary... I am not going to go into any Freudian enlightenment here but, once you face the cause of your fears, or stop growing physically,  the bad dreams fade away quickly to sleepy world of wonder and adventure.  \n\nGood Luck and enjoy.
