I Don't Want Nightmare AGAIN!!

Suffering so much today when I woke up.The nightmare...just torturing me whole night.Have you dreamed that your beloved left you?This is not the first time I have such a dream.Everytime the dream feel so real,just like what is really happened.The most torturing part is,everytime I wanna wake up from this kind of dream also failed,like some power is blocking me get out from the dream.Maybe I am alone at outside.I worry that the dream will come true everytime I have such a nightmare.I don't wanna tell my parents about this.I know they will worry me more if I say so.Oh God!I just wish I won't get such a nightmare ever.Can I???
