Prison
Psychological (Freud)
A prison in a dream usually embodies the sense of being shut in by one's own inhibitions, guilt, or social constraints. In depth-psychological terms it can stand for self-built walls behind which a repressed wish or an unlived part of the self lies confined.
Oriental reading
In traditional Islamic interpretation, prison often signifies a trial, illness, or a confining circumstance that hems a person in. Yet some interpreters also read it as a place of safekeeping that guards one from sin and harmful deeds, so that release foretells imminent relief and deliverance.
Death & Danger
Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
