You need a plot! Don't have a good plot? Get some friends to help you make one! And please,don't use the same old plot...its pretty shitty...and don't use any ideas like "The insane teen" which was been overused for a long time...here are some examples : Jane the killer,Nina the killer,Ticci Toby,Homicidal Liu,and many shitty...and I mean shitty others...
Also,please...and I mean please...don't use blood and gore for a plot...it just makes your creepypasta look unoriginal...very unoriginal! Also,make your plot have some sense...no magic or voodoo because that's been used to many times (and handled poorly).
