Lexx (1997)

Season 4: Episode 20

An asteroid mothership appears out of the blackness of space. A metal hatch opens and a tadpole-like creature shoots out and heads for the Lexx. Stan awakens from a nightmare in which he was eaten by Lyekka and discovers that the alien mothership is hovering outside of the Lexx. Before he can finish telling Xev and Kai what he has discovered, an alien who has assumed the physical appearance of Lyekka from Stan's dream appears on the Lexx.
