  We explore the real solutions to the Spherical Collapse Model in a non-flat
Universe with a Cosmological Constant, and observe a possible situation for a
fake or Ghost Collapse, in which an expanding overdense spherical region, turns
around and begins to collapse, turns around again after a finite time and
starts expanding. To make such a situation of spurious collapse feasible, we
make a linear redshift dependent correction to the standard Dark Energy density
term which is originally in the form of a cosmological constant. There is good
reason to believe in such a correction based on recent research which hints
that Dark Energy desnity evolves with the redshift (even becomes negative) when
fit to observational data.
