4 years ago I began having heart palpitations. I sought medical attention to discover that I had a heart murmur... but nothing to worry about. From that point forward I noticed that every heart palpitation was directly correlated to a death. So far, I've not been close to the person who died but I do know and am often close to a family member or friend of the person who died. It seems that the heart palpitations are stronger depending upon how close I am to the living relative/friend of the deceased. I've begun a log and have at least 30 of these events over the past few years. For a while I did not mention the feelings until after I found out about the death. Then as I became certain of the relationship I began to tell people I could trust each time I have the feeling. Is there any way to better hone into this. Is there some way I can begin to identify who in my life is associated with these feelings? I feel certain that if someone close to me were to die, I would have a much stronger sensation. And I also know that I can become more clear with this. Anyone have any ideas?

Even if it is possible to tell who it is pretty impossible to prevent it from happening.
I believe when a persons time is up it is up. Meaning if you tell them that you have a strong feeling they are going to die and they are planning a trip on a plane so they do not take the plane and stay home they could end up in a car accident. IF they are going to die from a medical condition a check up could help somewhat but still may not help in the long run. Then too, most people when you warn them of something they think you are a quack or a witch.
