A little "Lovey Dovey" zombie style to kick it off. T-ara
immortal guys with super powers fight for fun in "MaMa Beat" by LC9
Some monster experiments in "Pray" by Sunny Hill... actually this one is a little heart breaking
I don't remember if this one was on another list or not but I love it and y'all built such awesome lists that I had little to work with.
"The Art of Seduction" by Heo Youngsaeng. May not seem scary to us but I'm sure its the nightmare of many idol stars that they could become the prisoner of some delusional fan.
Have you seen the cult classic "Mommy Dearest"... This video may not really fit the Hallowe'en genera but Brown Eyed Girls released this musical (almost) version of that story with "Cleansing Cream"... it both horrified me and broke my heart at the same time. Like I said, I REALLY had to reach...all the other good one's were taken ㅋㅋㅋ
I hope y'all and @MattK95 enjoyed it.
