Ok... so we have two well known and proven suppositions:

1) Everyone is Puke.
2) Everyone is a figment of Ruatha's imagination.

Now, lets see what this means... Puke is part of everyone. Therefore, Ruatha is imagining Puke. Since Ruatha is part of everyone as well, this means that he is Puke. Therefore, Ruatha is imagining Ruatha. Is this the same Ruatha? Is Ruatha imagining himself? Perhaps. Perhaps there is more than one Ruatha in this imagination chain. So how could we tell who the real Ruatha is? Of course, if there is only one Ruatha, then this means that he is merely a figment of his own imagination, along with everyone else.
