About 6 months ago I started having very realistic dreams. So much so my girlfriend hears me talking in my sleep. I can recite the dream immediately after I awake and I start to remeber alot more within ten or twenty minutes. Thats not so much the issue, but the dreams themselves tend to be extreamly violent. Alot of guns, explosions, fast vehicle (cars/trucks, trains, helicopters) blood, death, and even full blown war. Iv never been in the military so I dont understand where this comes from. I dont have much time for tv, but when I do watch I'll watch cartoons with my girlfriends little girls. Also, on rare occasions, I have been able to actually realize im dreaming and Im able to control my actions, but there is no real dream at those times. It is me flying or jumping or swiming while breathing underwater, all at my own will. What might be going on?
