Dream Alien ship
The Dream Alien ship was a type of starship encountered in the communal dream experienced by the  crew in 2374. 

In the encounter, the initial Dream Alien ship attacked Voyager, it made multiple passes, forcing Voyager to reinforce shields with auxiliary power, while themselves unable to damage the Dream Alien ship, as their phasers were unable to penetrate its shields. As Voyager was about to launch photon torpedoes, it lost shields and was subjected to a localized dampening field, which caused a loss of power to the torpedo launchers. As their dampening field drained power from the remaining ship systems – engines, weapons, shields – compounded by the arrival of three more of these vessels, Voyager was forced to surrender, before the Dream Aliens began boarding their ship.
