Only child
A person who grew up without siblings — a life shaped by being the sole child in the household.
An only child in a dream is the dream's image of a life shaped by being the sole child in the household. The only child does not learn the early arithmetic of sibling rivalry; the only child also does not learn the practice of small daily reconciliation with a peer. The dream brings the only child when something in your life — a way of being alone, a difficulty with shared space, a strength at solo work — is being traced to the structural shape of the household you grew up in. An only child at rest in good solitude is the dream affirming the use of the original arrangement. An only child unable to negotiate ordinary friction with peers is the dream noting that a skill the early household did not require is now being asked for, and is going to have to be learned late.
