Neither rand(Dec64) nor randn(Dec64) works.

A simple solution would be Dec64(rand(Float64)), of course, but that doesn't use all of the significand bits; a more correct solution would require something lower-level.

rand() is now implemented. randn() could be implemented via Box–Muller, ideally as a fallback method in Julia Random itself.
