Yet another one in the "can't remember dreams" category here.. Stocked up on more Amnesia just now, maybe that has something to do with it!
I used to have dreams all the time where I'd be walking towards something and it's like I'm being pulled by a magnet to my left or right (I think it depends which side I'm laying on). I'd be giving it all I've got, trying as hard as I can to keep walking straight, but it was like I knew getting sucked out the door* would be disastrous..
* last one I remember, was where I was picking up a drink in a shop, then walk towards the till and the magnet would kick in, pulling me towards the entrance/exit on my right.. It was in my local shop and it was even an old layout from years before that time.
Come to think of it, I'm sure it's a metaphor..
