The following is a list of illusory starships.
Borg sphere Edit
In 2376, The Doctor enhanced his program so he could experience daydreams. In one of these, a Borg sphere attacked the ship and incapacitated the bridge crew. The Doctor activated the Emergency Command Hologram and took command. He tried to convince the Borg to stop their attack, but the Collective insisted that "You will be assimilated". The ECH then activated the photonic cannon and destroyed the sphere with a single shot. (VOY: "Tinker Tenor Doctor Spy")
Delta Rana warshipEdit

This illusion of a D'deridex-class Romulan warbird was created by Nagilum. It opened fire on the USS Enterprise-D, which returned fire and destroyed the warbird with a single photon torpedo. Captain Picard noted that "that was too easy" and and Data detected no debris from the Romulan ship. These were signs that something strange was going on. (TNG: "Where Silence Has Lease")
