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.

[on the holodeck, several crew members are recreating the room, its equipment and instruments from their visions step by step]
Counselor Deanna Troi: All right. You were lying on the table. You had a bright light shining in your eyes. Were there any smells in the room? Were there any sounds?
Commander William T. Riker: Yes. Yes, there was a sound. Computer, there were noises, coming from the darkness. Strange. Like whispering.

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.
