some thing wrong

I really feel like some thing wrong with me!In this four days,i already dream 4 type of bad dream when i sleep.I alway "saw" people born and die and of cause i got killing case in my dream too.First,i dream about my secondary school friend's daddy.He was crying.All of his family member were crying in my house and telling me that his dad is get sick!But when i arrive his house to meet his dad, i saw his dad is in emergency and just few minute......he pass away!Again, this is my second time saw people 'pass away' in my dream!I don't know what to do but only can talk to my friend,"This is one of our life,everyone must face this at the end of life, just try to accept it with your natural feeling."Everything is feel like real but it actually never happen in my life.I call my friend(never tell him about my dream),and his dad is ok!Thanks for God this just a dream.
Second, i dream about my classmate at college.Actually i don't likie this girl very much because her eyes is 'growth on her head'!!But that morning,i dream her in my dream again and saw her kill another girl in front of me.i never know what had happened us just saw her catch a girl,push her down and kill her in front of m.I try to save the girl even i don't know her but i just hold the knife that pierced in her chest.After this, the same thing happened again to me!She pass away in front of me.This time,i did't have any sad or scare feeling again when i saw this.I only can say when a "same thing" happened every day in our life it already become a custom to me.
Third,is my turn again!!This morning i dream about myself.But i never saw myself die in my dream but is about strolling around when i sleep!(in my dream) That already mid night but i hear my aunty said they saw my walked at outside the house alone and come back and continue sleeping beside her.They told my mum after this but my think that the ghost is enter my body and ask me go out at night.So start from that day, she not allow me stay alone at home,no more uncooked food,and cannot go to the dark place!This actually a very funny story for me but don't know why i still will feel very scare after i wake up!
I told all my friends and siblings about this because i really very scare some thing will happen to my family or my friends one day!But they said maybe i really too stress in my study and because i like to read novel that talok about UFO,Ghost,Killing and Detective!So,now all the story combine together and show to me again in my dream!I can accept this but can't accept my family or friends become the character in the story!!!NEVER & IMPOSSIBLE!
