(REAL PLOT SPOILER)
Sheppard touches some strang thing he comes across, after all checks by the doc(sexy keller) everything seems normal. But he starts to have nightmares, and this effect gets passed on throught people like a virus, through touch. The nightmares are all very strange and disturbing and feel 100% real, I know some stuff about each persons dreams/nightmares but lets leave that to the episode shall we? I'm expecting it to be similer to the episode with the wraith hilusination thing, with the episodes majority of parts being in the dream view of the individual person
Dont ask me how i know because i cant say. Just wait too see what the plot spoiler gateworld gets and see if it matches up
