If you express wise thoughts, this serves as further proof of your confidence. This dream represents the strength of your spirit and determination, which helps you move forward on your life's journey.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Walking on water" (page 466).
Walking on water in a dream represents one's strong faith, certitude and trust in God Almighty. This is particularly true if while waking one also speaks words of wisdom. Otherwise, walking on water in a dream also could mean clarifying a complex issue. Walking on water in a dream also could mean undertaking a dangerous venture and trusting one's affairs to God's protection. Irone walks back from the water to the dry land in a dream, it means that he will satisfy his needs or fulfill his intentions. In a dream, waking on water represents one's good intention, clarity and certitude. Walking on water in a dream also means unveiling a mystery, the need to trust one's affairs into God's hand, or it may mean approaching a danger, or it could mean that the accumulated pressures one is enduring are bearing heavy on him. It also means placing one's trust in God Almighty before embarking on a trip that could entail some danger. To walk on water, whether it is an ocean or a river in a dream also denotes good spiritual standing, religious assiduousness and strong faith, certitude and determination. (Also see Riuer; Water)
