This dream may symbolize a desire for connection and guidance from your deceased parents. The stroller represents your journey through life and the baby could represent a new aspect of yourself or a new project or idea. The fact that you don’t know whose baby it is or where you got it from suggests that this new aspect is still unknown to you. Your parents asking about the baby’s legs being fat could symbolize their concern for your well-being and growth. The fact that you only saw the left side of the baby could represent your subconscious or intuitive side, as the left side of the body is associated with the right brain. Overall, this dream may be a reminder to seek guidance and support from your inner wisdom and from your deceased loved ones.
