meaning of friend dream

i was with my best friend, amy, (who had moved out of the state recently) and her twin sister and a couple of my other best friends. we were in an area with lots of different pools on different levels of the grass but the water was black. all of a sudden we were looking for my best friend amy , i jumped in to the black water of one of the pools and saw her drowning! i tried to help her but she just stared at me and died . my friends pulled me out of the water and we left the area.
