its probably nothing bad. i think it means you never passed on a chain mail or you have watched a scary movie recently and some one died in it. So it might be you read the same thing or something it is still on your mind so you dream about it.
A different answer:
Characters in dreams often represent different aspects of the dreamer's personality. So the person you know in the dream could very well represent a part of yourself. For example, if the killer is someone from your work, the dream might be trying to say that your work is "killing you" in the sense of wearing you out, or taking up so much of your time that other parts of your life, such as family or social life, are "dying." Alternatively, if the killer in the dream is a bartender from your favorite pub, the dream might be warning you that too much drinking is "killing" you.
Whenever you get a dream like that .You should always take that positively. Positivity makes is a good thing to tackle those thoughts. This means that the person will have a long life.
Your answer is in your question."If the Grim Reaper kills you........""If he kills you, does that mean you are about to die?"No, if he already killed you......you are already dead...so how can you be about to die???????
nothing
The dream suggests a lack of information. You do not know as much as you think you know about someone in your life.
It certainly means you or someone you know is pregnant.
You or someone else that you know are thinking that they are pregnant and they want to know if its true.
it could mean that you want more with this friend
It's just a dream, if you want to know whether you're attracted to someone in your class then ask yourself.
The snake is representing someone that you know in the real world.
What does it mean if you cant find someone your looking for in your dream
The dream is not about this "someone you know." Instead, this someone represents yourself. Your own mind is showing you that you have lost track of a part of yourself.
Someone you know will die soon at night.
had a dream someone was getting out of jail
