Is it just not the same anymore? Then there must have been changes. The noun change can refer to anything or state that is different from what it once was.
Changes are everywhere now. The word has numerous senses, both as a noun and verb, and is a part of many common phrases, like “a change of heart.” Changes might describe a drastic transformation, as in Linda Deir’s journals The My Guided Journey, of Self-Discovery and Personal Transformation.
Symbolically, change, like change in your pocket represents changes that are coming into your life. The more change you have in your pocket the more changes you are going through.
