If you dream of walking on rugged terrain, it signifies your process of overcoming difficult situations in life. Such dreams often symbolize the mental stress or challenges you are facing. However, when you successfully navigate through this tough ground and reach a flat area, it represents your ability to overcome challenges and indicates happier times ahead.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Rugged terrain" (page 368) â resolved via the equivalent "Roadless terrain" entry.
Walking a rugged terrain, then suddenly seeing oneself walking through plains in a dream means overcoming one's difficulties. Walking through roadless terrain in a dream also means stress, adversities, toiling, stagnation of one's business, or it could mean looking into the ample opportunities of one's life. A roadless terrain in a dream also means fear of wrongdoing, straying from the path of righteousness, or walking the avenues of innovation. A road less terrain in a dream also means dullness or stupidity, while a plain in a dream signifies intelligence and keenness. (Also see Road)
