A Starfleet ensign who mans the conn of the Enterprise-D while the ship is trapped in a Tyken's Rift and its crew is slowly losing the ability to dream.
Ensign Kenny Lin is a junior officer aboard the USS Enterprise-D who appears in the fourth-season episode Night Terrors, set in 2367.
Lin is on bridge duty at the conn when the Enterprise finds the USS Brattain adrift with its crew dead by their own hands, and then discovers that it too cannot leave the rift that holds both ships. As the days pass without dreaming sleep, he suffers along with the rest of the crew from failing concentration, irritability and fear.
He is one of the ordinary crew members through whom the episode shows the ship coming apart, until Counsellor Troi and Data work out how to answer the aliens trapped on the other side of the rift.
