Not too long ago I found out I could precisely tell the time (hour and minutes) when someone asked me, even though I don't use a watch. It started as a joke, I would just say the hour out of the blue, like 13:37, and people thought it was strange and funny that I said 37 instead of 35 or just 30, but I 'guessed' right more than I guessed wrong to be considered just coincidence.
What I do is to close my eyes and try to see the numbers, sometimes they show up one by one, and then I have to form the hour pattern like of a digital clock, wow, thinking now, it would have been much easier to imagine the arrows of an analog clock, but then I would lose the precision of minutes.
When I woke up today I tried to figure out what time it was while still in bed, so I used many things into account, like how rested I was feeling, the clarity that came from outside, then I closed my eyes and tried to see the numbers. I saw a 4 and a 7, the 7 was specially insistent, but I wasn't sure whether it was 9 or 8 am, maybe 7.
I tried to visualize the 9 and expect some special sign to tell me that was the right hour, didn't have it. Then I tried with the 8, didn't have it either, I guessed it was 9:47 because I thought it was more likely to be, but when I looked at the clock it was 8:47
Maybe some people could try this too and see how well they can guess the time. The trick is to keep on looking at the numbers until you feel you're not controlling them, the moment you think that what you're seeing is unexpected but possible is the right time.
It takes a few seconds for the image to appear, and it's not so bright, I see something like this:
A letter would look kinda like this:
Peanut butter jelly time? (you know you were thinking it) I too have been able to acurately guess the time. usually I'd just guess kind of feeling what time it is instead of visulizing it in my head. biological clock?
