To dream of medieval times represents a dangerous situation in your life where there is always the threat of total failure. People around you may be very risky or irresponsible with you. The constant threat of failure if your behavior isn’t perfect. Feeling that your life is dominated by harsh circumstances. Stoical acceptance of suffering. Brutality.
Alternatively, medieval scenery in a dream may reflect how dangerously ignorant you feel people are. People that claim expertise with dangerous results. Confident or powerful people who scare you with their incompetence or ignorance.
Example: A woman dreamed of seeing medieval buildings in a field. In waking life she had a medical problem that doctors seemed to primitive to her to figure out. They gave her medication that never worked and kept trying to do other things that never seemed to work either.
Example 2: A woman dreamed of being in a medieval castle. In waking life she felt that her family was very controlling and domineering
