This is a strange thing but it happens to me sometimes.
I think of an incident for a few seconds and then doesnt too much concentrate on it and jumps to another topic abruptly and after some time I see that incident happening. I realise, oh, I thought about it and why I didnt give too much thinking on it!! however, if I concentrate too much that doesnt happen..
For ex: today when I was driving to work, I was a bit hungry and dont want to goto Maccee as yesterday only I went there! I was just thinking, what if someone brings some breakfast to office.. and then I forgot about it and went with the radio topic thought.
To my surprise, in our break room there were doughnuts!!
This is not the only incident however, I have had so many in my past..
