Thank you for your question. While the short answer to this is that it would be extremely unlikely for anyone to die in their sleep from not being able to breathe because of a dream or anything else, your own doctor
would be able to answer this question better than anyone else. He or she would have the most information about your other medical history and what concerns that might be in your situation. It is quite unlikely that you actually would die in your sleep in this fashion, as the body is prepared and has a number of defense mechanisms to prevent against this. Just like with seizures
, when all other systems shut down, the brain stem, the most basic control unit of the central nervous system, will usually keep the breathing going. In fact, the loss of consciousness may be one method in which the brain is able to shut down other competing activities to improve the essential functions. Please speak with your doctor more about this question, and to complete further testing if it is necessary.
