An antique may also reflect time honored values, traditions, wisdom or something you've inherited. Something you perceive to be genuine, proven, or worth keeping.
To dream of not liking or appreciating an antique suggests that you are moving away from outdated beliefs or old modes of thinking. You may be discarding or rejecting something from your past.
