  In this paper, we point out thermodynamical description of ghost dark energy
and its generalization to the early universe. Thereinafter, we find expressions
for the entropy changes of these dark energy candidates. In addition,
considering thermal fluctuations, thermodynamics of the dark energy component
interacting with a dark matter sector is addressed. {We will also find the
effects of considering the coincidence problem on the mutual interaction
between the dark sectors, and thus the equation of state parameter of dark
energy.} Finally, we derive a relation between the mutual interaction of the
dark components of the universe, accelerated with the either ghost dark energy
or its generalization, and the thermodynamic fluctuations.
