Previous Works

Is this all completely new?

There have been previous works, upon which this theory is built. There have been numerous studies on sub-parts of the sleep communication as defined above, especially on wake world stimuli being incorporated into dreams, lucid dreaming in general and its capability to change physiological parameters of the sleeping body (see chapter 2). Even the idea of using some sort of message coding is not new: In a study focusing on sleep world to wake world signaling by LaBerge for instance, sleeping persons signaled single Morse code signs to the wake world (LaBerge et al., 1981a), another study by LaBerge (1993) reported attempts to communicate from a lucid dream to the wake world by using sign language, recorded by hand muscle EMG, but also stated that at least at the time these experiments were conducted, existing technology was not sensitive enough.

Has there been a bidirectional messaging yet?

Some attempts have been made to combine lucid dream incorporations and body signaling, enabling a two-way exchange of signals. Strelen (2006) used a single high or low frequency tone to get incorporated into a dream, and used one predefined eye movement to signal back the detection of the high frequency ones. Oldis (2010) extends this in a theoretical manner by writing about the idea to use different stimuli cues and body signal cues for fixed messages like “I am dreaming” or “I am flying”, possibly being put into the context of so called “multi-player dream games”, i.e. multiple dreamers sending fixed cues to each other while lucidly dreaming. In experiments by Oldis and Oliver (2012) a simple light flash stimulus (light bulb on or off) and a predefined eye movement (looking twice to the right) were used for sending a signal from wake world to sleep world and back, and attempts to send a cue this way from one dreamer to another were claimed to have been successful once.

So what is new in this theory then?

However, a scientific sleep communication theory combining lucid dreaming, dream incorporations, body signaling and message coding, and describing the requirements for the exchange of arbitrary and with content filled messages with a sleeping person, in both directions from wake world into sleep world and from sleep world into wake world, is still missing and shall be introduced here.
