Nightmares???

these kind of violent dreams can be caused by several things: certain activities done before sleep, medication, stress, depression, recent intense emotional distress. a dream is just your mind on auto pilot and are really not significant but violent dreams can be triggered by what you are doing before you sleep. try a cool down period of thirty minutes before you go to sleep. try to just relax let nothing bother you read something you enjoy that makes you happy. this might help with the nightmares if not you might wanna seek a professional.
