Namaskaram.
One of my very close relative departed the earth. Next day, he came in his son’s dream and mentioned that he will be around there till puja (ritual) is completed. His son do not know about the soul’s journey and other details. Hence, I have ruled out that it may be due to thinking at his son’s sub conscious level. adiyen is wondering whether departed soul can communicate through dream?. I heard it earlier in that line.
