Sneezing in sleep occurs only when you are about fall asleep and about to wake up but when you are not aware of it. In other  words, due to your breathing rhythm, you can not sneeze in the REM states. For further information please refer to;\n\nhttp://www.anderson-college.edu/ pdf/documents/Healthservice.pdf

No, as the force (100 mph) would make your eyes pop out, also you should let your sneeze out and not keep it quiet as the pressure can do damage, burst blood vessels etc

Apparently it's impossible to sneeze and keep your eyes open at the same time....reflex thing.

yes.  you sneeze when something irritates your inner nose.  all that happens is that a little piece of dust gets in the wrong place, and you wake up sneezing--but this does not happen very often.  it is very rare

Well the fact is that humans cannot sneeze while asleep.\nSneezing requires a reflex mechanism, wherein the sensory nerves in our upper respiratory tract, esp nostrils, are stimulated by some stimuli (mechanical or chemical or other)and these nerves then go to the CNS (i.e brain) and as a final process excite the nerves which supply muscles pf our respiration and the pharngeal region and the man sneezes thus. You must \nknow that this reflex is a natural means to protect our sensitive upper respiratory tract from harmful influnces or, more appropriately, external influences, be it a solid or a gas or as a response to some infection. Now when the man sleeps, his brain is not working at its normal levels and so even though the man's nerves have some external factor acting upon them,\nno reflex is initiated and the man doesn't sneeze. You must also know that when the stimuli continues or crosses a particular \nlevel, it changes from an irritative agent to a source of maybe say pain and the the man can have a disturbed sleep; there is a threshold for every thing.

Yes it is healthy to sneeze! If you hold your sneezes in then you will totally mess up your sinus cavity, and have to have a $14,000+ sinus surgery. The thing about all of your functions is only if you sneeze so many time in a row. I was told if you continue to sneeze more than 12 times your heart will stop. \n\nSo, if you gotta sneeze let it out! My husband and I spent 4 sleepless nights after his surgery!

Does your heart stop when you sneeze?\n– Lauren K, El Cajon\n\nNo. The heart's rhythm is controlled by a natural pacemaker – the sinoatrial node, a group of cells located in the right atrium of the heart. These cells create an electrical impulse by pumping charged particles out of the cell and then allowing them to flow back in. Conducting cells transmit the electrical impulse to all parts of the heart to initiate muscle contraction. Sneezing does not stop this electrical activity.\n\nHowever, the nervous system and circulating hormones, such as adrenaline, alter the rate of the electrical activity in the sinoatrial node to increase or decrease heart rate. Just as exercise leads to an increased heart rate, sneezing works many muscles; therefore it is possible for a "sneeze attack" to increase heart rate.\n--------------------\nSherry Seethaler has a doctorate in science education and is a UCSD science writer and educator.

Looking at the sites in our Heart category, your heart keeps pumping blood throughout your body from when you're a baby in your mother's womb until the moment of death. Your heart beats all day and all night, all the time. When you run or play hard, your heart beats faster. When you're asleep, your heart beats slower, but it doesn't stop. If a person needs heart surgery, doctors hook the patient up to a machine that pumps blood for the heart. Only then is it safe for the doctor to stop the heart in order to operate. When you sneeze, the muscles in your abdomen, chest, and throat are all involved. And, even though you might not notice it, your heart is working too.\n\nEarl

I doubt it can damage your brain.  But it is bad for you.  You sneeze to expell germs or something irritating your sinuses, so not allowing yourself to sneeze ("closed mouth") allows that germ or whatever to stay inside.  Just let yourself sneeze!

No, but if you can keep your eyes open, you will not sneeze

Just relax.  This is probably just a sub-conscience reaction to not wanting to be heard sneezing.  Nobody should think differently of you as long as you make sure that your hands are clean.

A sneeze is the fastest known action that a human can perform.  It is involuntary and can make the head mover VERY sharply.  Maybe our eyes close so that we don't get anything in them when our head jerks forward?  Dust, leaves, branches, etc. would be both painful and dangerous if they got into our eyes while we were moving our head at high speed.\n\nAccording to Wikipedea:\nIt is almost impossible for a person to keep their eyelids open during a sneeze, although some rare individuals report having little if any trouble doing so. The reflex of shutting the eyes serves no obvious purpose: the nerves serving the eyes and the nose are closely related, and stimuli to the one often trigger some response in the other.

No it doesn't kill brain cells. Sneezing is an automatic reaction to an irritation of the nasal passages. You should never suppress a sneeze. It can cause major ear problems, eye problems and does your vascular system no good at all.\nAs an example of how strong a sneeze is, I fractured my eye socket when sneezing and it wasnt a suppressed sneeze. I couldn't believe it. My socket was fractured and the tear duct popped out of the corner of my eye!

Some people can sneeze with their eyes open and some people can’t. Sneezing is a reflex and so is closing our eyes. We have no control over whether or not we close our eyes when we sneeze. Some people don’t have reflex, so when they sneeze then their eyes won’t close. Some people try to close their eyes so when they sneeze their eyes won’t pop out. Your eyes don’t really pop out. People without the reflex to sneeze with their eyes open can try to train themselves to sneeze with their eyes open. One good way to do this is if when you sneeze you hold your eyes open.\n\n    People think that when you close your eyes when you sneeze that you are blocking germs and bacteria. That is not true because your eyes deal with germs all the time. If you close your eyes during a sneeze, then it is just a reflex. During this part of the sneeze, we tense some of our muscles. The tensing (tightening) of our muscles causes our eyes to shut.\n\n    People that sneeze a lot can prevent sneezing. If you feel a sneeze, then use saline solution. You can also softly hold your nose at the end. These things can help your body remove things it does not want without sneezing.\n\n    No one knows the reason you close your eyes when you sneeze. There are many possibilities. Some people think it is to protect your eyes from flying goop. Most doctors think that it is still a reflex, or we just can’t help it.\n\n    Sneezing is very good for you and your body because it removes things from your body like bacteria and germs. It also is good because it keeps the tubes that carry the air from your nose to the lungs healthy. Sneezing makes your nose clear when you have a cold. If you used to hate sneezing, then I hope this has changed your mind.
