No number has an incentive or compulsion to appear to any person.

The number 222 and many other numbers are in your environment — clocks, prices, dates, measurements, etc.

The number 222 is remembered as being seen because the number has a notable meaning for you — an emotional significance, a personal meaning, or a notable construction of the number (composed only of digit 2s). Therefore, when you notice the number in your environment you give it special attention as being noteworthy. It is that additional attention that lets you remember seeing the number when you don't remember seeing other numbers. If 222 had no special meaning or significance for you, it would not be remembered just like other numbers are not remembered.

In other words, the meaning of seeing 222 so often is the very meaning you have assigned to it.
