Dream of unknown Death and silent Grief

"I had a dream that someone had died, but I don't know who it was. I remember being in a house with a few people, and everyone seemed to already know. Nobody was saying much. I kept waiting for someone to tell me what happened. At some point I was looking through an old box of photographs. I found one of a person I couldn't recognize, but in the dream I somehow knew them. Then I was outside, standing near a bus stop. A woman was crying beside me, and I remember putting my hand on her shoulder. I wanted to say something, but I couldn't think of anything. The strange part is that the dream suddenly became very ordinary. I was in a supermarket choosing bread, and I remember thinking that I should probably be somewhere else. Then I heard someone say the person's name. I turned around, but nobody was there. I woke up feeling sad without really knowing why."
