Movie in a weird house with weird people like a cult or something

Hello, everyone

I’m trying to remember the name of a movie that I watched few years ago. I don’t remember the actors or anything like that. I only remember that the guy is invited to a house, and something like a initiation happens to him in the beggining, I think it’s in the basement, some crowd clapping to him. Then after that he walks throught rooms, in some room it’s happening like a reunion and weird things happen, I don’t remember exactly what happens, but I think he sees something supernatural. I think he tries to leave the house but he couldn’t. In the end of movie I think is like a company that provides this kind of experience and he’s forced to join this company. Sorry for my english.
