Dead sand does not exist. Sand is an abiotic substance of the earth that is neither dead nor alive. However "dead" sand could mean sand that is not subject to erosion of any kind, and thus just stays in one place for a very long time.
I think the second idea above is getting towards the correct answer. I've come across this term in drilled boreholes, and I assume it to mean that the sand does not flow, i.e. it has some degree of compactness or cementation.
The opposite to this (also seen in borehole logs) is 'live' sand, which I interpret as 'running sand' or 'piping sand', i.e. sand which is not bound together and tends to flow as soon as it is brought to the surface.
