I think it's the will of the deceased that causes an attachment to the yellow ray vehicle that would cause something like this:

47.13 Questioner: What stimulus would create what we call an Earth-bound spirit or a lingering ghost?

Ra: I am Ra. The stimulus for this is the faculty of the will. If the will of yellow-ray mind/body/spirit is that which is stronger than the progressive impetus of the physical death towards realization of that which comes, that is, if the will is concentrated enough upon the previous experience, the entity’s shell of yellow ray, though no longer activated, cannot either be completely deactivated and, until the will is released, the mind/body/spirit complex is caught. This often occurs, as we see you are aware, in the case of sudden death as well as in the case of extreme concern for a thing or an other-self.

"sudden death" is how a lot of organs are donated.
