I keep having this happen to me...
I will be listening to the audio of something (say a podcast or a show on TV) while reading something else (a totally un-related article on the internet or something), when suddenly someone on the audio will say a totally random word (let's say "Parchment") at the exact moment that I'm reading that word on the screen.
I would understand if it were really common words that were syncing up like that, but it's often more obscure, not-so-everyday words that it happens with that freak me out when it occurs.
I'm beginning to think that aliens are beaming something into my brain and if I were to write down the word each time, the secrets of the Universe would be revealed. Either that or I'm just crazy.
