The phenomenon you're describing, where you consistently see different "mirror numbers" on the clock, may be attributed to a psychological effect known as the frequency illusion, or the Baader-Meinhof phenomenon. It occurs when something you recently learned or noticed appears to crop up constantly in your environment. In this case, your heightened awareness of mirror numbers leads you to notice them more frequently.
Mirror numbers, or palindromic numbers, are those that read the same forwards and backwards, such as 12:21 or 10:01. The fact that you perceive different mirror numbers every day could simply be a consequence of chance and the infinite possibilities of combinations on a clock. The numbers you observe are likely a random occurrence, but because you are specifically attuned to mirror numbers, you are more likely to notice them.
It's important to note that such experiences generally do not have any specific cosmic or universal meaning. They are a result of the human mind's tendency to search for patterns and assign significance to them. While it can be intriguing or even entertaining to find patterns in everyday occurrences, it's crucial to approach them with a level-headed perspective and not read too deeply into them.
If you find yourself overly preoccupied with these mirror numbers or experiencing distress due to this phenomenon, it may be helpful to discuss your concerns with a mental health professional. They can provide guidance and support to help you better understand and navigate your thoughts and feelings.
