Well, some people say some are caused by junk food...try eliminating that from your diet.

I get rid of them telling 4 people about it so it wont happen in real life. Thats wat my mom usualy tells me to do. :)

1. Identify the cause of your nightmare. It can be hard to puzzle out what it means, so it’ll be hard to identify what causes it. Try to write your nightmare down as soon as you wake up. Even if they are the same every time you have them, there might be some differences and these are usually clues that will help you get to the root of your bad dreams. It’s also a good idea to consult a psychiatrist. They are trained to handle cases like recurring nightmares and will help you identify the root of your problems. If the problem is related to a past trauma that you have subconsciously buried, they will help you overcome and accept it, so you won’t be troubled by it anymore. Psychotherapy is still a very good weapon against psychological problems, and nightmares certainly have strong psychological roots. 2. Try therapies. There is a treatment studied at the University of New Mexico called “Imagery Rehearsal Therapy” which does not involve medications. The treatment involves helping the clients change the ending of their nightmares while already awake, and make them non-upsetting. The patient is then instructed to rehearse the new ending associated with the changed dream. 3. Change your night-time habits. Changing your habit before and while sleeping may help lessen the frequency of your nightmares. Refrain from getting too much caffeine before you sleep. Also, try not to eat too much, in order to prevent extra brain activity during sleep. Be sure that you are not tired or fatigued, and when you do sleep, try to be in the most comfortable position as possible. Improving the quality of your sleep will go a long way to making sure you have pleasant dreams. http://www.howtogetridofstuff.com/health/how-to-get-rid-of-nightmares/

slow down on chocolate before sleeping.

Think happy thought before bed time.

It depends. You can try watching what you are eating before bed. (especially to close to bedtime) You could try meditation before bed. (if you don't know anything about meditation you can look it up online)

All dreams have meaning. Or rather, it's better to say that we can derive meaning from all dreams. Freud showed that our memories of dreams change rapidly after we awaken. People asked to write down details of the same dream seconds, minutes, and hours after they first woke reveal details and identities slowly changing as time passes. Thus it's not necessarily the dream itself which has meaning, but out unconscious interpretation which does. If you've having nightmares, they have a lesson to teach you. Learn the lesson and the nightmares will go away. Perhaps the easiest way to eliminate nightmares is to consciously will yourself to confront the "scary thing" in the dreams before you go to sleep. A simple desire to do so -- or possibly even just reading this message -- will probably be enough, since dreams are highly succeptible to suggestion. Most people find that when confronted, nightmares become much better mannered. In fact, often the source of the nightmare is frightened by being confronted and runs away. Remember that ALL characters in a dream are aspects of yourself. You created them. A thing in a dream which is scaring you loses its power when confronted the same way other fears lose their power in your ordinary waking life when confronted. A healthy, meaningful dream life is an integral part of staying sane. Look at these nightmares as an opportunity for personal growth rather than something to fear.

By thinking positively on such an occasion.

Don't eat peanut butter before bed.
