Dream of Siblings
Dreams of brothers and sisters reflect both sides at once: rivalry and cooperation. Getting along with them, or doing something together, is read as support arriving from those around you, while quarrelling marks that it is time to settle where interests overlap with someone close. A sibling you have not seen in years can also mean news or contact. That said, this dream does not foretell anything about your actual siblings, and it comes with the same meaning to people who have none. Read it as standing in for whoever is close to you now.
Siblings are a bond given rather than chosen, so a dream of them brings in the people who stand beside you without your having picked them. Traditional dream lore saw siblings as branches split from one root and read them as figures who support each other. In practice, though, they usually stand in for whoever is walking beside you now, or bumping up against you, rather than an actual sibling.
Readings by Situation
Getting along or doing something together
Read as support arriving from the people around you. Old lore counted harmony among siblings as a household rising. Hands are about to join work you had been carrying alone.
Quarrelling with a sibling
It signals that your share overlaps with someone close. The closer the root you grew from, the easier it is to end up wanting the same thing. Write down what overlaps and it usually turns out the problem was never the person but a share nobody divided.
A sibling you have not seen for years
It can mean news or contact. Old lore read someone long absent appearing as word passing between you. It is a fine season to reach out first.
A sibling ill or in trouble
Not a warning that anything will happen to them. It marks that someone is on your mind, so asking after them serves better than letting the worry grow.
The sibling here is less the actual person than a seat beside you, so do not read it as something befalling them. In that case, read it as a picture of a colleague you walk beside or a rival you measure yourself against.
