Have you ever felt like some event is repeating, or that you have heard that exact same thing before, or that some event is repeating, or that you have heard that exact same thing before? For those among us who saw the Matrix, we know that this creepy sensation is called "déjà vu". For those of you who saw the Denzel Washington movie of the same title, you have my sympathy.

I often experience déjà vu when driving. For example, I will be driving up to a little set of traffic lights on the way to uni, and a Beyonce song will start playing on the radio. A week later, I drive through those traffic lights again, and the exact same song is playing on the radio.

This time though, I experienced déjà vu in a whole new way. I logged onto my messenger account, and noticed that there was a contact on my list called 'Dan', and 'Dan' signed in and out a little too often... the chime goes 'Dan' has signed in, only to repeat a few minutes later. I looked at my messenger list at the contact labelled 'Dan', and by the contact I really mean four contacts all with the exact same 'Dan'. There were four contacts one after another, all called Dan. No 'dan' or 'DaN' here, just four contacts called 'Dan'.

It got even more confusing when I realised I don't know who two of those Dans are, and had a sneaking suspicion the third is actually called Michael - but it did give me an idea.

What would it be like if EVERYBODY changed their msn contact name to 'Dan' for one 24 hour period. How confusing would it be. Especially for people like me, who don't often commit email addresses to memory in the same way I don't commit mobile numbers to memory. People everywhere would be having conversations with Dans they never knew existed. Every contact would look the same, it could quite possibly be the largest collection of 'Dan' ever assembled. Talk about déjà vu.

What does everybody of the déjà vu Dan for a day idea? Spread the word, 'cause this idea is so crazy it just might work!
