Llixgrijb is a character from Will Coleman and Pat Perrin's book, The Jamais Vu Papers. Llixgrijb is a generic creature who exists in a no-dimensional universe, and who receives no stimulation whatsoever. What is a sentient being to do? Llixgrijb's way out of its prediciment is to dream, and thus create a universe of its own. The distinction of whether or not the universe is physical or not is moot, because Llixgrijb exists in its universe. It doesn't matter if it is real or not.
Anyway, that's where the name of this blog comes from.
