Why am i having Nightmares Repeatedly?

It has been about a week now,and im STILL having nightmares.For Example,(takes place on Halloween Night)Im playing outside,And i yell for no reason,(usally is HIGH gr and tall trees and no porch)then i go to the Short Gr,And see Tombstones and an Unfinished porch against my house! Then,Out of the gr(it chases me and right when it bites me i wake up) comes a ghoul!Then,I Wake up,and fall back asleep.Here is my Next Nightmare:Me and my 4 friends are playing Hide-And-Go-Seek.We are hiding behind a board beside my house.Well,i am.My other 2 friends are sitting in the gr.Then,i yell.Then,(one of my friends)Brandi says,"Ian,why did you do that.You know what will happen.Im Dissopointed in you." Then,the ghouls come and get us.Then my Alarm clock wakes me up
