#1 Paid Lifestyle App in the United States. Developed at Harvard and MIT, Sigmund allows you to influence the content of your dreams. Sigmund adapts the most advanced scientific studies of dream modification (via during-sleep verbal stimuli) into a user-friendly app. You influence the content of your dreams by selecting verbal stimuli to be played during your REM-phase sleep, below your waking threshold. Visually strong verbal stimuli, such as "beach, orange tiger" as well as personally-meaningful subjects that relate to activities, people, and places, such as "date, girlfriend, Paris" are especially likely to be incorporated into your dream content during sleep, and Sigmund allows you to select from hundreds of recorded dream elements. __________________________ The only App on the App Store that allows you to select from and broadcast **actual recorded spoken words** during REM sleep, below your waking threshold. Actual spoken words are the only verbal stimuli that research has shown to be capable of influencing dream content (Journal of Sleep Research, Schredl, et al., 2009). There is no scientific evidence that mere ambient noises or "soundscapes" are meaningfully incorporated into dream content, and all research in this area has focused on the effect of verbally-spoken word recordings on dreaming. Over 1000 actual recorded spoken words are included to select from. __________________________ Scientific Research Research has shown that external stimuli presented during sleep can affect dream content, thus reflecting information processing of the sleeping brain. In the Journal of Sleep Research, Schredl, et al., (2009) describe what has become the standard experimental procedure: A stimulus is presented during rapid eye movement (REM) sleep and the sleeper is later awakened to elicit dream content. The effect of various kinds of sensory stimuli on dream content has been studied, including sinus tone (Dement and Wolpert, 1958), personally-meaningful spoken words and names (Berger, 1963), neutral words (Hoelscher et al., 1981), light pressure applied to the leg (Nielsen, 1993), and olfactory stimuli, such as the scent of flowers (Schredl, et al., 2009). Overall, dream studies indicate that some kind of information processing of external stimuli is present during sleep. The incorporation of verbal stimuli, such as spoken words and names, into a sleeping subject’s dream content is of especial scientific and psychological importance. In 1963 the British Journal of Psychiatry published the seminal study in this field, “Experimental Modification of Dream Content by Meaningful Verbal Stimuli”, which undertook a controlled experiment in which tape-recorded spoken words and personal names were randomly presented below the waking threshold to sleeping subjects during the rapid eye movement phase of their sleep-cycle. Each recorded word was played in four-second intervals for four repetitions during the REM-phases of the subject’s sleep. The study found that when dream recall was elicited afterwards, the “stimulus appeared to have been incorporated into the dream events… as manifested by the ability of the experimental subjects and an independent judge subsequently to match correctly the names presented with the associated dreams more often than would be expected by guessing correctly by chance alone” (Berger, 1963). Incorporation rates of the verbal stimuli into the dream events ranged between 35% and 45%, excluding instances where the subject reported that the recorded voice was heard and instances where the subject did not report having a full dream. At Iris Sky Labs we realized that with the advent of smartphones—which fundamentally are programmable computers capable of broadcasting pre-recorded sounds at pre-determined times—it was now possible to re-create the essential experimental conditions of these sleep studies and dream research in the comfort of a user’s own home. © Iris Sky Labs LLC |
