Creepy dream story

The other night I had a crazy dream about people getting eating by other people. Granted, I've had dreams about zombies (I do love me some zombie movies) but nothing like the one I'm about to share. In my dream, I see there are multiple people in a barn or a room that is dark, probably basement-like room. I see some familiar faces, and then all of a sudden I see a person with razor sharp teeth (I will call him magician) and a hat, almost like a magician's hat. He has a creepy smile, but more due to the sharp teeth. When he "eats" people, the person changes into a monster like him, but very briefly. If you have seen the movie smile, you'll remember how creepy of a smile the person has before they die. Well, after being "eaten" these people would return as themselves but had a creepy a$s smile, clearly not themselves, and would go on about their lives as though nothing ever happened, into the public. In my dream the next thing I remember is being in sort of a corporate office, or maybe a police station but there are people with suits and ties, like a white collar type of setting. Me and another person (their identity is unknown) are both realizing how many individuals are hiding behind these new identities and realize that they are trying to "convert" as many individuals to become these creatures, almost like vampires. We see this "magician" who makes his way into the men's bathroom following a man who is also going into the men's restroom. The business man comes back out of the restroom but has the same creepy smile on his face. Me and this person that I am with start leaving this office setting without making it obvious that we know what's going on. Plus we don't know how many people are now "changed". Then we move into the parking lot where we start to drive away from this place. This is basically where my story ends.
