Blood dreams alarm people more than almost any other image, so it is worth saying at once that they are common and that they diagnose nothing at all.
Two things belong at the top of this entry. Blood appears in dreams frequently and it tells you nothing whatsoever about your health or anyone else. Where interpretation has anything to offer, it concerns three long standing associations: life and vitality, family connection, and the price paid for something.
People wake from these dreams shaken in a way they do not from most others, and the reason is not symbolic. Blood signals injury, and the alarm response is doing exactly what it evolved to do. There are also ordinary triggers worth naming: a recent injury, a nosebleed, a blood test, a period, a difficult medical appointment or simply a graphic film watched too close to bedtime. When any of those applies, the dream may be nothing more than the day repeating itself.
A nurse, a squeamish teenager and someone who has recently been in an accident do not meet this image on the same terms, and any reading has to begin from which of those you are. People who work around blood daily report it in dreams without alarm and often without meaning.
Whatever else is said about it, this entry makes no claim about your body. Dream interpretation is a tradition of reading images, and if something about your health genuinely worries you, that belongs with a doctor and not with a dream dictionary.
