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.

The opening log entry Captain Picard makes says the Enterprise has entered a dense globular cluster yet all external shots of the ship in this episode show a normal star field with few near by stars. Globular clusters have stars extremely close together. The external shots of the ship should have shown hundreds, if not thousands, of near by stars. See more »

Awfully good.
27 November 2014 | by (Bradenton, Florida) – See all my reviews

Riker is having a lot of trouble sleeping and goes to see Dr. Crusher about it. A bit later, others are complaining about their sleep and the Doctor finds that there is something wrong with their REM sleep. Counselor Troi, however, comes up with an answer when she sits these crewmembers down and has them talk about their dreams. Using the holodeck, they all have similar stories and it soon becomes apparent that they were all aboard some other ship being poked and prodded! Using the ship's computer, they are able to determine that two of the crew have disappeared! One re-appears later and he's been eviscerated! Obviously whoever is doing this 'research' isn't too concerned about the damage they do to the subjects. But, they cannot locate these beings as they are in some other phase or dimension. So how can they stop these weird folks from poking, prodding and killing them?

This is an awfully frightful episode--far more so that normal for the show. In addition, the suspense is high and it makes for a very good installment of the series.
