Dreaming about being unable to move can range from being slightly inconvenient to legitimately terrifying - and it's a dream that we've pretty much all experienced at one time or another. Whether we're trying to run or fight, but are finding that our motor skills are failing as we do so, or whether we are simply laying down, completely paralysed and vulnerable, the dreams are said to mean the same things - that we are questioning our worth and, to be frank, fear that we might be useless, or that we are simply aware of the fact that, while we are asleep, our muscles actually are literally paralysed temporarily, which is what the phenomenon of "sleep paralysis" is all about. So, dreaming about this kind of thing can either mean that we have insecurities in the real world, or that we are concerned about the fact that we really are vulnerable and exposed whilst sleeping.
