Sleepwalking

Sleepwalking or somnambulism was the act or practice of walking while asleep.

In 2375, Seven of Nine began to sleepwalk due to the proximity of a Borg Vinculum, resulting in several interruptions to her regeneration cycle. 

In 2376, after Tom Paris was released from Alice's influence, he described his behavior while under "her" control as being like sleepwalking.
