Telepathic contact

Telepathic contact was a Time Lord ability to form a telepathic link between multiple minds for high-speed conversations and decision-making. The ability was seen between different incarnations of The Doctor. (DW: The Three Doctors) It is also possible between two different Time Lords. (BFA: The Apocalypse Element) A similar ability was shown by the Doctor when his sixth incarnation on Space Station Chimera contacted his second incarnation, currently on Earth in the same time period, via the astral plane, but it's unclear if this is the same ability, or a side effect of enhanced memory from past incarnations. (DW: The Two Doctors)
