I am going to make a real life horror aventure with friends! need help for scares!

1. Start off slow. A bump here, a creak there...
2. Cut the power at one point. The room with the breaker box should have blood writing on the wall but so they can only see it when they turn on the lights.
3. Make sure they're not packing heat... or knives or anything. Don't want to get yourself killed over a little prank.
4. Make sure you document it in some way! I want to hear all about it! (night shot video cameras ftw!)
