To dream of an old age nursing home represents feelings about a situation almost being over. Sensitivity about about losing time, having to settle down, or having to get realistic about getting older. Feeling that an eventual ending is inevitable, but that there is still lots of time.
Negatively, a nursing home may reflect feelings of being too old to do something anymore. Stress or frustration with having to care about someone who is too old or impotent to care for themselves anymore. Feelings about death or failure being inevitable while you try to be enjoy anything else at all.
Nursing homes in dreams are common to people who have elderly parents that they don't expect to live for much longer.
Example: A woman dreamed of trees being cut down in front of a nursing home. In waking life her father died and she felt bad about having lost the remaining time she felt she had left with his father.
