I came here to make you dance tonight....

I want a true Halloween experience. Okay, I get it. It's a bad holiday and yadda yadda but I've never so much as been to a costume party. Is something spooky and exciting that hard to come by any other time of the year? Yes. So can someone please help me find something scary as hell to engage in on Halloween this year? I will even dress up or whatever it takes to have a good time and experience my first Halloween ever.
