I've heard some suggest it's "wrong" to watch horror films or read thriller books, etc because putting that "imagery" into your psyche.. I disagree with this. I think anything that harms your emotional state attracts negative things. I love horror movies and watching one puts me in a great emotional state, the way I'd feel after a roller coaster ride (a good movie anyway!). Good vibes are good vibes, no matter where you get them from. Only you know if something is damaging to your mindset.
