To dream of something being abolished may represent feelings that some area of your life is censured. It may also reflect fear of being involved with certain behavior. Feelings about restrictions that have been placed on you.
Example: A man dreamed of walls being abolished in an apartment building. In waking life he was living in Nazi Germany during Hitler’s totalitarian rule and privacy rights were being eroded.
Example 2: A woman dreamed of street signs being being abolished and replaced with signs that listed the 20 words people were legally allowed to say. In waking life she was living under the Nazi rule while experiencing radical restrictions on freedom.
