The part of a healthy human brain responsible for deciding what's real and not doesn't function during sleep, which is why dreams can be truly terrifying or astronomically erotic. It isn't until we wake that we can make sense of an unconscious experience and determine reality from a fantasy.
Some individuals, like hunky wrestler Tristan Mounts have experienced so much trauma that they exists in a conscious world where illusions exist, making truth indistinguishable from imagination. Tristan attempts to cope with this rare condition through professional wrestling and by facing fear head-on, but how much hope is there for him when nightmarish malevolent giants like VanGore stomp the conscious plane of existence.
The only question is which part of this nightmare is worse, being stripped down in public, sadistically tortured beyond pain and flexibility limits, facing a 7 foot giant inside a wrestling ring or not knowing if any of this is real?
