Today, I wake at 5am in something of a funk. I'd been having a bad and very vivid dream in which aliens disguised as IT marketing executives were trying to take over the world. Their technology was a combination of an MRI scanner and high speed wireless network that set up resonances in the brain and took control.

Trouble was, it didn't work very well. At the big industry launch where the aliens were going to reveal the tech and sell it to us as a great consumer boon, it became clear during the demo that it wasn't actually ready. The press conference quickly degenerated into a battle between the alien marketing directors and journalists – some of whom were taken over by the brain rays and turned on their colleagues, with varying degrees of success. During this rampage, the aliens dropped their disguise: they still looked like Americans in suits, though.

The details of the dream were rather engaging. The launch took place in a modern museum of antiquities, some of which turned out to have been planted thousands of years ago by the aliens in preparation for the take-over, and I can remember in dispiriting detail how the tech was supposed to work. I woke up just as I was being physically equipped with a dongle: I'll spare you the details, but I was very glad to find myself awake and un-modded.

It doesn't take a Freudian to untangle those themes – from the tin-foil hat brigade running scared of Wi-Fi to the tendency of the wireless industry to oversell itself on matters it doesn't really understand, it's all standard stuff. And as for aliens with Powerpoint; that makes rather more sense than Roswell ever did. I'll leave it to you to decide which journalists are really Pod People.

I don't think 7am is too early to call my therapist...
