meaning ofr dreams weird dream

weird dream:
I was told by someone I didnt know, a man, that I had to strangle this boy that was in front of us. He was aproximately teen aged. Next thing I know, he's face down on the ground and I have my hands on his neck squeezing the life out of him. Seconds before I go past the point of no return, I let go of his neck and am relieved I didnt kill him, but I am left with the feeling that now I might be in trouble if the man who told me to do this comes back and sees I didnt kill the boy. End of dream (thank God!)
We were outdoors, on a dirt road, no cars or houses around. I didnt recognize either person in my dream. It was summertime. The young boy appeared to be of mexican or native decent.
