  We extend the Dinh-Sibony notion of densities of currents to the setting
where the ambient manifold is not necessarily K\"ahler and study the
intersection of analytic sets from the point of view of densities of currents.
As an application, we introduce the notion of exotic periodic points of a
meromorphic self-map. We then establish the expected asymptotic for the sum of
the number of isolated periodic points and the number of exotic periodic points
for holomorphic self-maps with a simple action on the cohomology groups on a
compact K\"ahler manifold. We also show that the algebraic entropy of
meromorphic self-maps of compact complex surfaces is a finite bi-meromorphic
invariant.
