Just as it is possible to have different kinds of a real thing -- stars for example come in white dwarfs, brown dwarfs, red giants, and more -- it is possible to have different kinds of an imagined thing. Stanislaw Lem illustrates:
The banality of existence has been so amply demonstrated, there is no need for us to discuss it any further here. The brilliant Cerebron, attacking the problem analytically, discovered three distinct kinds of dragon: the mythical, the chimeral, and the purely hypothetical. They were all, one might say, nonexistent, but each nonexisted in an entirely different way.
