I keep having this dream...what does it mean?

well dear, dreams like this often have to be interpreted by the dreamer, because it will have a very personal meaning relative to your life alone. Now, the facing your future part could be as general as the fact that simply everyone dies. Or perhaps it is a warning that someone close to you will be ping over soon. Do you recognize the voice at all? Perhaps it is someone you see in your life as a guide or wise elder you respect. Perhaps it is signifying that after your own death you have a greater mission and purpose to fulfill. this is kinda off subject, but if you like reading, you should read a book called "On a Pale Horse" by Piers Anthony.
