There are far too many possibilities to provide any meaningful answer based only on the information in this question. Very generally, dreams of recently deceased loved ones are a normal part of the grief process, while gruesome nightmares of dead bodies express the dreamer's fears and phobias. See the attached link, below, for extended discussion and more examples.
when we speak to a dead person it is often something we wished we said.. or someone we wished were there to advise us.. our dreams are a review of our subconscious... where all our memories are stored.... speaking to dead people is no different from speaking to livng ones in our dreams because those we know are stored in our subconscious
She Never Knew Me was created in 1976.
The dream's interpretation depends on the identity of the dead girl. She represents some part of yourself, but what that part of yourself is may be very different depending on whether the dead girl is someone you knew in the past, a deceased celebrity, or someone from the pages of history. On the other hand, if you have no idea of the identity of the dead girl, that means that you have no knowledge of an important part of yourself.
