Sometimes I see my dead grandparents in my quite lucid dreams, and while everything seems almost normal, I suddenly remember that they are actually dead. This realization creates a unique, surreal feeling inside the dream where I still see and treat them like living beings BUT know internally that they are long gone. These types of dreams aren’t very pleasant and leave a lingering sensation of something out of place once I wake up.

There is an esoteric belief (knowledge?) out there according to which some part of dead (one of their 7 bodies or something like that) remain on earth among the living as long as at least one living person actively remembers them. However, it is never EXACTLY them as they were in real life. It’s just a lingering presence of some energy part of them, and as the time goes by it can become influenced by many things and grow into something quite different. It’s pretty much fed by the memories of the living, like an entity, plus other energies out there can add to it something that was never a part of the actual person who is long gone. Anyways, it’s just a theory, but worth pondering about for those who do believe in such things
