There is no compelling reason to think that they aren't real. We have evidence every other night of Landel's ability to brainwash people. We know they are attempting to do the same to us. We also know that patients who vanish return as visitors.

Anything presented as fact, or the most reasonable assumption that future action should be based on, should be able to withstand continual judgment. Moreover, we hadn't discussed the topics of the visitors specifically. I'm interested in hearing your opinions on the matter.
