Strange, fighting dreams, very lifelike?

recently ive been studying dreams for my lucid dreaming and ive found that common interests in real life appear in dreams...so if you are stressed or angry about something you may have dreams that feel like you are releasing your anger or being a victim of anger....also if you are going to bed thinking about fighting, violence or death it is common to dream about things on your mind... if you are worried about it try watching happier tv and reading non violent books.... go to bed earlier and think about happy, safe and calm places as you go to sleep, hope i helped dude
