Psychoprojective telepathy

Psychoprojective telepathy is a telepathic ability of the Halanans. It apparently entails projecting a seemingly solid image of ones' self, which may act out subconscious personality traits.

On a visit to Deep Space 9 aboard the USS Prometheus (NCC-71201) in 2370, Nidell lost control of her psychoprojective telepathy, allowing Fenna to appear to Benjamin Sisko.
