Halloween is my favorite time of the year.
For better or worse, horror and Halloween are almost synonymous in the mind of the modern individual. The original Halloween (Samhain - pronounced 'SOW-win') was not about scaring people but respecting our ancestors.

That said, scaring people is a lot of fun. So I'm going to help you scare your players today with a few useful links. Happy Halloween!
While not scary specific, Tabletop Audio has many frightening atmospheres to use in your pen and paper games! Click 'Horror' under the banner. The artist behind the site creates a special track each year to celebrate Halloween. This year, that track is 'Nightmare'.

Possibly one of the most immersive websites out there, Beksinski.pl is the official website of the Polish artist, Zdzislaw Beksinski. Turn your volume up and spend some time clicking through the website for inspiration. The floaty black things take you to various pages. The galleries are breathtaking; combined with the organic, breathing feel of the website and the immersive music, it's easy to get lost in them.
You may never come back.
Mr. Gone makes character sheets for World of Darkness. I imagine if you're interested in horror RP you've played it or intend to play it at some point. There are also some free fonts and graphics to make your own sheets with or use otherwise.
Hope these help! Be sure to listen to the Halloween episode of RnRP!
