If you take M=X={0}, then M is dense in X since the closure of M is equal to X. However, there exists an element of X, namely 0, which is NOT a limit point of M since no epsilon balls around 0 contain a point of M distinct from 0, which contradicts your definition of M being dense in X. Could you please explain this?

I.e., if M closure is equal to X.

M is dense if M union D(M) is X.
