Second Sight (episode) | Memory Alpha | Fandom
Sisko falls in love with a woman visiting the station, but she is not what she appears to be. Up late, Jake Sisko can't sleep either. He had a nightmare he is reluctant to share with his father, but eventually reveals it was about running around the corridors of the station, unable to find his father. Once he feels better, he returns to sleep, adding as a footnote he misses his mother.
