Think you might want to research and study up on Telepathy.
Telepathy is the ability to transmit or recieve thought packages, read minds and also manipulate others thoughts, most often people with minor telepathic abilities are only able to link with their spirit guides or another telepath due to lack of sensory perception.
Telepathic suggestion is to transmit a specific thought onto another without the others persons knowledge of it,where as broadcasting would be an entire group rather than an individual.
The channels of telepathy can be recievable, transmittable or even both, it is done on a subconcious level.
You should be able to heighten this ability by meditation and sensitivity levels.
Hope this helps.
