Hive mind
A hive mind, group mind or gestalt consciousness was a collection of separate, distinct organisms with a shared consciousness, which may or may not have meant that the creatures were without individuality.
In the case of a hive mind, though, the general idea was that the same mind existed in multiple, separate beings or that each being's mind is linked with the others, allowing all organisms to know what is happening to just one organism of the hive. Also a trait of a hive mind, each individual of the hive referred to itself as "we" or "us" rather than "I" showing that it spoke for the entire hive mind.
Hive minds often had a shared memory. (DW: Last of the Time Lords)
The Ood, the Bane and the Family of Blood were psychically linked but still retained their individualism. Some hive minds even had leaders. The Amaryll were lead by the Alvega Controller, the Wirrn had a leader, the Rutans had a Queen and the Shalka were led by Shalka Prime.
Because of their abilities and similarites with known hive minds, both the Vespiforms and the Hervoken may have been hive minds as well. (DW: The Unicorn and the Wasp, NSA: Forever Autumn)
Torchwood theorised that Weevils had a low level telepathic ability to share emotions. (TW: Combat)
Richard Harries speculated that all beings had a collective memory that could be accessed. He experimented into this using rats. (EDA: The Banquo Legacy)
The Psionovores had an undefined natural energy existence, but could coalesce into a gestalt physical form, given enough will. (BFA: Minuet in Hell)
