The 11:11 Phenomenon

How often have you noticed the numbers 11:11, 12:12, 10:10, 22:22, 12:34, 2:22, 3:33, 4:44 or 5:55 popping up all over the place? These number sequences are not necessarily only time prompts. They can also be number sequences, like 333, 1111 etc. To your mind, is this a coincidence, or are they too frequent to be random? Perhaps you are puzzled or amused by this phenomenon? Possibly even a little bit nervous? The question everyone is asking is "What does 11:11 mean?" and "Is there a reason for this?" And there certainly is.
