Srimad Bhagavatam Canto 05, Chapter 14, Text 17

SB 5.14.17

kadacin manorathopagata-pitr-pitamahady asat sad iti svapna-nirvrti-laksanam anubhavati.
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sometimes the conditioned soul imagines that his father or grandfather has again come in the form of his son or grandson. In this way he feels the happiness one sometimes feels in a dream, and the conditioned soul sometimes takes pleasure in such mental concoctions.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Due to ignorance of the real existence of the Lord, the conditioned soul imagines many things. Influenced by fruitive activity, he comes together with his relatives, fathers, sons and grandfathers, exactly as straws gather together in a moving stream. In a moment the straws are thrown everywhere, and they lose contact. In conditional life, the living entity is temporarily with many other conditioned souls. They gather together as family members, and the material affection is so strong that even after a father or grandfather passes away, one takes pleasure in thinking that they return to the family in different forms. Sometimes this may happen, but in any case the conditioned soul likes to take pleasure in such concocted thoughts.
