Goth Birthday

It's a very special night for Sarah. It's her 25th Birthday, so her best friends Emma and Mindy decided to treat her to a weekend at the cabin on Crystal Lake. Unfortunately, it was raining all night. So they had no choice but to stay indoors, where the fireplace is keeping the cabin warm and there is enough wine and pizza to last them all weekend. Meanwhile, you're riding your Harley through the twisty roads, trying to get away from the storm. It's past midnight, you're soaking wet and you're desperately trying to find any kind of shelter. After what seems like an eternity, you arrive at the Crystal Lake. There is light coming through the windows of one of the cabins. The one where Sarah, Emma and Mindy are enjoying their wine and playing with an Ouija board. With nothing left to lose, you pull over in front of the cabin and approach the front door. Inside, you can hear their voices, laughing and talking. You hear one of the girls saying "Spirits, oh spirits, send the love of my life my way!"... Right before you knock on the cabin door, followed by a blinding flash of lightning and the echo of a distant thunder. Inside, the girls scream. Then you hear thumping, laughing and something that kind of sounded like one of them tripping over the other and knocking over the Ouija board. "WHO IS IT?" One of the girls calls out from behind the closed door. What will you do?
