I dreamt of my late father inlaw. We were all eating in the kitchen & the bell rang. When my husband opened the door, it was my father-inlaw. He was full of smiles & very happy. When we told him to eat with us, he said he was very full. When my husband said to him,he should stay with us, he said he can not because everyone is waiting for him & we must work towards coming to him. He was dressed in white & full of smiles. Please advise me what this dream means?
