I was a boy in my dream (though I'm female)

I saw this dream in August last year. I was a little boy (9 - 11 years old). I was lost but parents found me and we were driving somewhere. Father was driving a car. I remember I had other nationality and lived in another country than in real life. We were driving somewhere to countryside, as if we were hiding from someone. Then I remember I was sitting alone in a room, playing with toys and started hearing some strange noise from other room. I went there. When I entered the room I saw several men standing in there and I saw a big basin and my mom in there (inside the basin. Her blood was dripping from it). She was cut into pieces and her blood was everywhere. They killed and cut her. I don't know where the father was. Also I remember that I ran away from them. This is the most horrible dream I've ever seen :(

I would like to know that that could mean.
