I would call a vet...
If it is like that, cold and not breathing, yes, it is dead.
it means that it is dieing
It may be excited. Most small animals breath rapidly when they are being held or if you are reaching out for them. It's not bad or contagious but if your hamster is breathing unevenly, bring it to the vet immediately!

The Buteyko method strives to remove the bad habits of over-breathing and to replace them with new habits of slower, shallower breathing, called "reduced breathing."
There are several methods for picking up a hamster. The two safest methods are: 1) Lower a container into the cage and let the hamster climb into it. This method is safe and keeps the hamster from biting your fingers. 2) Cup your hands together and slide them under the hamster to lift it out of the cage. Or slide one hand under the hamster and cup your other hand over the top of the hamster.
