Younger Sibling
A younger sibling stands both for what you must look after and for the part of you that is not yet grown. Caring for them means responsibility increasing, or work leading juniors. Seeing them do well is a good omen that what you poured out comes back as results. A sibling hurt or crying, by contrast, signals someone weighing on your mind — if a particular person worries you, asking how they are beats interpreting the dream.
A younger sibling is the one person who arrived after you and stayed. Traditional reading treated the younger as the seat of responsibility, and separated the meanings by whether you cared for them or clashed.
Readings by Situation
Looking after a younger sibling
A sign that responsibility grows but you carry it well. Tradition read caring for those below you as your standing rising. Take it as a time when something is handed to you.
Fighting with a younger sibling
A sign that you are colliding with your own unfinished side. Tradition read conflict with the younger as frustration aimed at yourself. It is not a forecast of a real quarrel.
A younger sibling ill or crying
A sign that something you failed to tend is on your mind. It does not forecast anything about that person. Calling to check on them is worth doing regardless.
Seeing a younger sibling do well
A good omen that the effort you put in bears fruit. Tradition read those below you prospering as the household rising. It is also read as news about a junior colleague.
A dream of a younger sibling does not foretell anything about a real one. It is often drawn by a sense that you must look after someone, so count whose share you have been carrying lately.
