You're not going to want to hear this, but, they will get you, they are pretty good at breaking groups apart cause we learned that they are under the mindset the one in the middle is easiest to scare haha.
Its all good fun, but its very intense, you will either come out of a house in tears, in laughter, or in shock. Last year was my first year, and I had a blast, I surprised myself to the fact I wasn't scared, only one out of the five houses really got to me. But my friend, she was screaming the wholeeee timeee. So I was laughing each time she got scared, I was apologizing more than I was screaming (Due to my friend pushing me into everyone. I also discovered I don't want to be caught in a dangerous situation with her, in the Chucky house she pushed me into Chucky so she could run.)
But, I loved it, and it helps to bring someone you know is a lot more scared than you are.
