Is it possible to sneeze during sleep?

Do you just wake up and sneeze and then right after fall back to sleep, or do you sneeze while sleeping or is it simply not doable?

Yes it's possible,  and you have likely done it and simply don't remember. We frequently enact behaviours during sleep which are not encoded into memory,  thus we cannot recall them at a later date. You may have had a nonsensical conversation with a partner in the night at some point and they don't remember it; this is another example. 

I would suggest you are less likely to sneeze during sleep because you are still and so won't encounter as many irritants. But it's definitely possible.
