I'm not positive if this is strictly our finely tuned intuition, but I have noticed a stunning internal clock in myself. I'll do things like forget to set my alarm to wake up the following morning but still wake up at the proper time despite my scattered sleep schedule, be able to predict what time it is without actually knowing the the real time, just guessing, and I suppose always being at the right place at the right time. Things just fall into my lap, and I attribute some of that "luck" to this sort of mental preparation I do at the start of each day -- visualizing what and when a life event is going to take place and how I'll act in the given circumstance. I'm always there in perfect timing and it freaks me out sometimes. Any other INFJs notice a strong internal clock in themselves?
