What will happen when a dromion meets with a ghoston?

A new kind of excitation is defined as ghoston, because it is invisible at most of time and can only be detected when it meets with other objects. In order to show it in detail, we take the Boiti-Leon-Manna-Pempinelli (BLMP) equation as a concrete example. Its solution, obtained by means of the multilinear variable separation approach, shows a novel and interesting phenomena that a ghoston will emerge once it meets with a dromion, and when it leaves the dromion with time passing, the dromion will remain identical but with a phase shift, and it becomes invisible again
