To dream of concrete represents ideas, plans, or situations that are permanent. A solid foundation or absolutely knowing that something in your life can’t fail. An area of your life where there is absolute certainty. Confidence in a situation or relationship that doesn’t go away.
Negatively, concrete in a dream may reflect feelings of being stuck with something permanent. An area of your life is too solid or secure to do anything a about.
Example: A young man dreamed of hanging off ledge like his life depended on it. In waking life his father whom he lived with was close to death and he knew he’d have to move and start a new life if he died. The concrete ledge reflected the solid foundation of his home life that was “on the edge” of changing for good.
Example 2: A woman dreamed of falling into the ocean and scraping her hand on as she climbed out. In waking life she hand badly injured her hand in a accident and felt that her cast was irritating her and scratching her while she slept. The may have reflected the solid permanent feeling of the cast.
