Telepathy
is direct transference of thought from one person (sender or
agent) to another (receiver or percipient) without using the usual
sensory channels of communication. With a sender and receiver both open, direct, now-time communication is possible but this generally occurs between one telepathic person and a child, animal or plant (as they are more open). The biggest frustration for those who have opened the realms of telepathy is being able to talk with another mind, without them talking back. After much concern personally about being able to have telepathic conversations with people who had no recollection of the topic, I found two other types of telepathy :
Latent Telepathy is described as being the transfer of information, with an observable time-lag between transmission and receipt.
For me personally, this means one would generally be talking to a persons past state of mind (usually around 10 minutes lag) which has already moved into the subconscious, thus the person not "hearing" the words.
Precognitive Telepathy is described as being the transfer of information, through Psi, about the future state of an individual's mindThis sort of telepathy you would be conversing with the subconscious mind with around a 10 minute lag, whereas the person cannot consciously hear you. The conversation topic generally comes to the persons conscious mind soon after that although memory of telepathic communication generally dissipates.
