Frequently, with Sleep Disordered Breathing (SDB) such as Obstructive Sleep Apnea (OSA), your sleep is disrupted to the point that you are unable to get into a deep sleep. This prevents dreaming or only allows fragmented dreams. When you start using your CPAP, you are able to get to the deep level of sleep required to dream. You may experience a lot of dreams at first, and then taper down to a normal amount. This occurs due to the body getting used to deep sleep again. Once you are used to “normal sleep” again, dreams should be more normal in frequency.
