Recent dreams containing sgt

I had a dream that 2 people died my wife and one of my sgt's in the military and i was going threw my NCO's things as if i was looking for something? my lil brother was in the dream as well he was in the house with me but he was cleaning and washing clothes? then he gave me this huge gun and it had like a time keeping mechanism on the end of it. then a LT Colnel nocked on the door i answered it and he said he new Sgt Duran and asked if he could come in? it seemed as though he blamed himself for his death he stayed very briefly and then left. After that i got this overwhealming feeling of my wifes death and i cried i walked out of the living room and feel to my knees in what seemed to be on rocks and water i then got up and started walking to the end of the road which seemed to have lead to some sort of beach or waterfall? but then someone wanted to stop me and a woman gave me a towel and i turned around and walked back to the living room which seemed to be sitting in the middle of this road that lead to the waterfall or beach? as i got closer my grief became greater and then i awoke.
