Commander Riker has not been sleeping well but Dr. Crusher can't find anything wrong with him. He is constantly exhausted and has images of object in his mind that he can't quite place. He is not the only one with a sense of deja vu and with others, manages to piece together what has been happening. It would seem they are being taken from the ship during their sleeping hours by a race conducting experiments on them. Who they are and what they hope to achieve is unknown but everyone agrees it must be related to the inter-dimensional hole in space that is somehow being created in one of the cargo bays.

Troi, Riker and the rest are in the holodeck trying to remember what's been happening to them; they're asking the computer to recreate a table they all remember being on. When Riker remembers having some type of restraint over his chest, Troi asks the computer to create a restraining arm "attached to the right side of the table at the midpoint." The computer creates a steel restraining arm attached by high steel panels to both sides of the table. See more »

ST:TNG:131 - "Schisms" (Stardate: 46154.2) - this is the 5th episode of the 6th season of Star Trek: The Next Generation.

This episode continues the smart and rich writing that the 6th season is known for. Riker is having problems falling asleep, which Dr. Crusher thinks is caused by a lack of REM sleep (harkening back to the 4th season episode "Night Terrors").

However, what Dr. Crusher prescribed doesn't seem to be working. And other crew members (such as Worf and Geordi) also start feeling fatigued and remembering vague but threatening images based on objects aboard the Enterprise. Even Data has a lapse in time in his internal chronometer.

When the affected crew come together to try to piece together what was happening based on the objects they seem to remember, they use the holodeck to recreate it. And what they see is more horrifying than they can imagine.

Trivia note: watch out for Data's poetry reading, especially his "Ode to Spot" his cat! Also, Ken Thorley returns as Mr. Mott.
