Within the biblical tradition, a mattress or bed is more than a physical object—it is a recurring symbol of rest, refuge, and the state of one's soul. Scripture frequently uses beds as metaphors for spiritual rest in God (e.g., Psalm 4:8: 'In peace I will lie down and sleep, for you alone, LORD, make me dwell in safety'). A pristine, inviting mattress in a dream may represent divine protection, spiritual security, or a season of peace, while a soiled or broken mattress can signal spiritual unrest, guilt, or a call to repentance (Psalm 6:6: 'I am weary with my groaning; all night I make my bed to swim; I drench my couch with my tears'). Searching for a mattress may reflect a longing for spiritual belonging, rest, or reconciliation with God.

In Buddhist thought, a mattress can symbolize the impermanence of comfort and the importance of mindfulness regarding attachment to physical ease. The Buddha renounced luxurious beds as part of his path to enlightenment, emphasizing non-attachment. Dreaming of a mattress may prompt reflection on one's relationship to comfort, the transient nature of pleasure, and the cultivation of inner peace regardless of external conditions.

Culturally, the mattress is a universal symbol of rest, privacy, and personal space. Its condition often reflects one's socio-economic status, sense of security, and well-being. In many societies, the mattress is also tied to intimacy, family life, and the boundary between public and private spheres. Seeing a mattress in an unusual place may suggest a disruption of personal boundaries, exposure of private matters, or shifts in social roles.

In Hindu dream interpretation, a mattress can symbolize the state of one's mind and karma. A clean mattress may indicate good karma, peace, and readiness for spiritual progress, while a dirty or uncomfortable mattress may suggest mental unrest or unresolved karmic issues. Searching for or moving a mattress can symbolize one's journey through samsara, seeking a place of rest or spiritual fulfillment.

In Islamic dream interpretation, as detailed by classical scholars like Ibn Sirin, a mattress (farash) is a multifaceted symbol linked to one's spouse, home life, and personal comfort. A clean, well-kept mattress may signify a harmonious marriage or domestic tranquility, while a dirty or damaged mattress can warn of marital discord, instability, or personal discomfort. Searching for a mattress may indicate a quest for stability, a suitable partner, or a new home. Moving or replacing a mattress can symbolize significant changes in one's domestic or marital circumstances, including separation or new beginnings.

From a psychological perspective, a mattress is a powerful symbol of support, comfort, and vulnerability. It represents the foundation upon which one rests, both physically and emotionally. A clean, comfortable mattress suggests a secure support system, healthy boundaries, and emotional well-being. Conversely, a dirty or damaged mattress may point to unresolved emotional issues, anxiety, or a lack of support. Searching for or moving a mattress can indicate life transitions, a desire for greater emotional security, or the need to establish new boundaries.

Spiritually, the mattress is a symbol of the soul's resting place and the need for inner peace. It can represent the sacred space where one connects with higher consciousness during sleep or meditation. A comfortable mattress suggests alignment and harmony within the self, while discomfort or exposure (such as a mattress in a public place) may indicate spiritual vulnerability, imbalance, or a need to retreat and restore one's energy.
