Pain

S1, E17: A few members of the Destiny crew begin experiencing disturbingly realistic hallucinations bringing their personal fears or desires to life. Some worry that the stress of life on board the ship has finally begun to trigger nervous breakdowns. After isolating those affected Dr. Tamara Johansen (Alaina Huffman) believes the hallucinations are related to the last planet the away team visited. But just as she thinks she’s contained those at risk, she discovers the cause of the hallucinations is transferring to other members of the crew. When the hallucinations become life threatening, she and the crew must track down whatever is causing the episodes before someone dies as a result.
