My Mom & Dad Died in My Dream? Any Clues About That?

Last Night, Well more like this morning, I had a dream about my mom. I had came home and my house was messed up and it was very dark. I saw my dog run in her room so I followed him. When I got In there I saw my mom laying in her bed. I had called earlier and it went to voicemail, so I figured she was asleep, but when I looked at her head and there was a gush of blood under it, but she was still breathing. I heard a noise behind me and it was someone walking toward me with pliers and before he hurt me, I woke up. The boy I knew and his bestfriend had just moved beside me, but the strange thing is, a few days ago I had a dream about my dad. He was laying on the couch and my great uncle and Aunt's friend both killed him, oddly it was with a screw, not a screwdriver, but a little screw. Any Ideas???
