Sam is ready to walk up to the cow outlined in the smoke on the planet he was on. The setting affected him by: he was new to the planet so he didn't know a lot about it. He was more interested in the unknown than afraid. He liked the new and dangerous things.
As he was walking up to it, a new shape was forming. At first, he couldn't recognize it but then he saw that it was making a human being. Creating conflict by: at this time he didn't know it was a hallucination so he didn't worry about anything. Again this was a new planet so he wasn't used to the changes and dangerous objects.
It was real!
As he walked up to the other Sam, he noticed that he could only communicate to him through his mind.
It was a hallucination, Sam!
After he got back, the corridor master was not happy that he was out there that long. He said that if he is a troublemaker then he is not wanted with them on that planet.
Sam explained that what he saw was not a hallucination, it was real. He explained what he saw and what it's purpose was.
The corridor master then said that Sam was experiencing a hallucination and it wasn't real. The corridor master was getting ready to send him home because of the troubles he was causing.
