Storyline

After John Sheppard is drawn to and touches a crystalline substance on a planet he and his team are exploring, several members of the expedition begin to have nightmares. Teyla dreams that Sheppard turns into a Wraith and feeds on her; and Dr. Jennifer Keller dreams she is called to sick bay to treat Teyla who is in excruciating pain while Sheppard looks on, apparently enjoying her suffering. Sheppard himself is fine but when the nightmares begin to spread to other members of the crew and one dies as a result of what happens in her dream, finding a solution takes on an even greater sense of urgency.

Trivia

In their meeting, Sheppard quietly asks, "Did I have a goatee?". This is an homage to Star Trek: The Original Series: Mirror, Mirror (1967), where Kirk, McCoy, Scotty and Uhura find themselves aboard a parallel Enterprise in a mirror universe, in which Spock is sporting a goatee. Going back further, this can be an homage to many "B Sci-fi movies" of the 1950's. Specifically, Forbidden Planet. See more »

Dr. Keller states that while she can give McKay something to keep him awake, that eventually he'd would die from pulmonary failure.

What the writers likely meant to have her say was "cardiopulmonary failure" as simple pulmonary failure (respiratory) would not be an issue from remaining awake for an extended period of time. See more »
