Last night dream is really disturbing and I just wonder what does it say??

My sister and me had taken mother at home, dead, we did put her on the couch and I did make a bed for me besides her, in the head end, it
was that I could lean my head toward mothers. I did go out of the room and when I come back my mother had taken my place, I went out
and told sister to come and look, she only shook her head and sighned to me to be silent.
I went out for a while and now when I come back mother was sitting on the couch still with closed eyes, I again went after my sister to come
and look, she only looked without saying anything, and now mother started to talk, here I awoke myself....
