To dream of a washing machine represent personal changes that you are noticing in yourself. Your personality or who you are is being noticed changing. It may also reflect personal growth or self-improvement that you have initiated. A washing machine may be a sign that you are choosing to give up bad habits or change yourself.
Example: A woman dreamed of seeing a baby waving at her inside an old-fashioned glass washing machine. In waking life she was pregnant and felt that having a baby was making people notice her personality changing as she prepared for the birth.
Example 2: A man dreamed of him and his wife riding a washing machine ride at amusement park. In waking life he and his wife were pretending to be parents as they prepared for a birth. The washing machine ride reflected their attempts to deliberately change their personalities to be more responsible as they tested their parenting abilities.
