Halloween Party Help

I might throw a Halloween party and I am 11 years old and I am just starting Middle School. So I want to impress alot of people and my bf. And another girl is having a Halloween Party and I really need to hurry so she won`t invite my friends. Please help. If you want stuff about my house so u can give me some ideas here:
~Woods behind my house
~SOME halloween decorations
~3 story house
Other stuff:
Should we all watch a scary movie if the others aren`t scared of HALLOWEEN with micheal myers in it?
