Posture dream meaning is explained below using 3 different sources. Each interpretation is shown with its source.
Interpretation 1 — Dr. Mıchael Lennox
It is an accurate reflection of your underlying mood and expressions of the unconscious.
If your dream reflects particularly good posture and an erect spine, you are expressing a profound sense of well-being. This can also be a compensation for neglecting a holistic approach to how you move through life. Bad posture could be a clue that something outside of your conscious awareness is throwing you off entirely; time to check on the foundations of your lifestyle.
Interpretation 2 — Dream Explanations - Anonymous
If your posture is erect, then you are feeling proud and -composed.
If your posture is hunched, then this represents shame or insecurity.
