Axions and Axion-Like-Particles (ALPs) are theoretically well-motivated dark matter candidates that, due to their large occupation number can be described as oscillating classical fields. At low energies, axions and gluon-coupled ALPs present an interaction with nucleon densities that modifies the axion or ALP's field dynamics, and it is going to induce a very interesting phenomenology. In this talk, we explore in a general setting, the possible modification of direct dark matter experimental sensitivities caused by the presence of the Earth. We will also discuss the time scaling of the field in different physical situations and some exotic scenarios where high nucleon densities can change the vacuum expected value of the axion's field inside the nucleon sources.
